What is the difference between a solar thermal panel and a photovoltaic panel?

By | News | No Comments

The operation of solar panel as well as photovoltaic panel is entirely dependent on the sun. But, there is a difference between these two panels in the recovery and transformation of solar energy: very advantageous energy source because of its free and its availability. Estia Synergie gives you in this article the difference between a solar panel and a photovoltaic panel.

 

First of all, we should known that solar panels convert solar radiation into heat and photovoltaic panels produce electricity from the sun’s rays.

 

Solar thermal panels

We install a solar panel when we want to take advantage of the domestic hot water in our house. Sometimes it is also used for heating. In its mode of operation, this model exploits solar radiation in order to convert it into heat.

These solar thermal panels transform sunlight into heat by radiation, this is the principle of the greenhouse effect. Then, the heat is transmitted by conduction to a heated water circuit, will be directed to a balloon that will transfer heat to the domestic water heater. The disadvantage is that when the water heater is “at good temperature”, the panels continue to produce without being able to conserve the energy produced.

 

Photovoltaic solar panels

Photovoltaic solar panel installations convert sunlight into electricity using the photovoltaic cells. With the inverter, the direct current will be converted into alternating current and connected to the electricity distribution network.

The energy drawn from the rays will first be transformed into electric current. The electricity produced is ready for use, but can also be stored in batteries. Solar photovoltaic panels represent a real ecological solution for the production of electricity. They do not emit greenhouse gases and the materials used are recyclable. In addition, this kind of installation guarantees a long service life. Indeed, a photovoltaic panel generally has a lifespan of up to 30 years.

 

In both cases, it is always essential to carry out a study before any installation; and Estia Synergie accompanies you and guarantees you quality installations.

Definition of energy

By | News | No Comments

Energy can be defined as an ability to modify a state or to produce a work causing a movement or generating electromagnetic radiation, light, for example or even heat. In short, energy is the faculty of producing a job. Energy is found in all the processes of the earth and the elements of nature: heat, wind, life, movement.

Today, our societies are demanding more and more energy to satisfy our energy needs: at home and at work. The importance of the availability and use of energy is such, that these concepts are used as scales of the development of societies

Most of the energy used in Côte d’Ivoire is obtained from hydroelectric dams. The availability of this energy source is often problematic and expensive; which poses serious problems for users.

However, there is an alternative that would reduce costs and be more respectful to the environment. This alternative is solar energy which is a renewable and green energy.

Renewable energy is a form of energy that is periodically available to humans and is able to use and transform.

The solar energy that is the most abundant and available of all renewable energies is inexhaustible.

Estia Synergie Côte d’Ivoire offers innovative and sustainable solutions in solar energy to reduce your electricity bills.

Can Solar Panels and their efficiency be affected by rain?

By | News | No Comments
1- Can Solar Panels be affected by rain?
Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun’s energy using photovoltaic cells. All solar panels are waterproof, and in the rare case that they are damaged by water. The rain also helps to keep your panels operating efficiently by washing away any dust or dirt. And you are usually protected by warranties from Estia Synergie.
2- Can the efficiency be affected due to rain?
The cells of the solar panel don’t need direct sunlight to work; they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. Photovoltaic panels can use direct or indirect sunlight to generate power, though they are most effective in direct sunlight. Solar panels will still work even when the light is reflected or partially blocked by clouds. They do work in cloudy weather; they just do not perform as well as they would on a bright sunny day. Though estimates range, solar panels will generate about 10-25% of their normal power output on a cloudy day.

A revolution with irrigation

By | News | No Comments

A revolution is taking place in how water is being pumped in remote locations beyond the reach of electric power lines. Solar power has proven to be an ideal way to lift water for drinking, sanitation, stock tanks, and irrigation.

Solar Photovoltaic (PV) panel is one of the the simplest possible way to generate electricity beyond the reach of power lines. It has no moving parts and last for decades with virtually no maintenance. Solar power is no longer an expensive, experimental energy source.

Estia Synergie offers an effective solution: “Powered Drip irrigation system″ especially designed for farmers, who do not have access to conventional power and has small land holding.
The water used for watering plants comes from the storage tank of 50M3 of water, intended for agriculture. When the drinking water tank is full, the pumped water is sent directly into this storage bin for agriculture. This regular availability of water will increase and guarantee agricultural production.

Solar-powered drip irrigation

By | News | No Comments

Solar-powered drip irrigation is the marriage of two systems that have been shown to have an enormous independent impact, but have rarely been used together in a well-documented fashion. Drip irrigation is an extremely efficient mechanism for delivering water (and fertilizer) directly to the roots of plants. It increases yields and allows for introduction of new (potentially high-value) crops in regions where they could not be sustained by rainfall alone. Solar-powered (photovoltaic, or PV) pumps save potentially hours of labor daily in rural off-grid areas where water hauling is traditionally done by hand by women and young girls. They are durable and immune to fuel shortages, and in the medium- to long- term cost less than traditional diesel-powered generators. These technologies allow for production of market garden vegetables during the dry season, providing a much-needed source of both income and nutrition.

 

Due to the ever-increasing population in the world, water in general is becoming an increasingly scarce resource on our planet.

Much of humanity’s freshwater is used for crop irrigation at one side; and on the other side, it’s used for inefficient watering systems. Although efficient watering systems such as conventional drip are available, they are not often user by farmers due to their high cost, especially in economically less favored countries.

 

Solar-Powered Drip Irrigation

The Solar-Powered Drip Irrigation of Estia Synergy will change this panorama, because it offers a very efficient irrigation system as well as an inexpensive installation simple system; it allows millions of farmers to obtain an increase of their production while using less water.

In fact, the water used for watering plants comes from the storage tank of 50M3 of water, intended for agriculture.

When the drinking water tank is full, the pumped water is sent directly into this storage bin for agriculture. This regular availability of water will increase and guarantee agricultural production in different ways:

  • Irrigation of land
  • Increase the production of fruits and vegetables
  • Provide fire protection
  • Guarantee off-season production

 

The bladder is the perfect option in these areas. It can be installed directly on the ground without much investment and will supply water to irrigated land.

Solar energy: a factor of poverty reduction

By | News, Uncategorized | No Comments

Solar energy could help reduce poverty. David J. Grimshaw and Sian Lewis talk about its progress, its potential and the problems it poses.

Increasing access to energy is essential for ensuring socio-economic development in the world’s poorest countries. An estimated 1.5 billion people in developing countries do not have access to electricity, 80 percent of whom live in sub-Saharan Africa or South Asia.

The problem is greater in remote areas: 89 percent of the rural population in sub-Saharan Africa lives without electricity, more than double the proportion (46 percent) of urban areas.

For these people, even access to a reduced amount of electricity could lead to beneficial improvements in the areas of agricultural productivity, health, education, communications and access to clean water. .

Options to increase access to electricity in developing countries focus mainly on increasing central energy produced from fossil fuels such as oil, gas and coal, by expanding the electricity grid . But this approach has few benefits for the rural poor. The extension of the network in these areas is either impossible to achieve or too expensive.

This strategy does not contribute to the fight against climate change either. Energy is already responsible for 26 per cent of global greenhouse gas emissions, and while most of this energy is produced in industrialized countries, by 2030 developing countries will use 70 per cent cent of total annual energy more than developed countries.

There is therefore a clear need to find ways to improve access to electricity in the developing world, which benefits the poor and low carbon – solar energy could be a solution.

More than half of the world’s people without access to electricity currently live in sub-Saharan Africa. In this zone, “the number of people without access to electricity will continue mechanically to increase until 2025 or even 2040” according to the Montaigne Institute when the population growth there is “faster than the rate at which the populations have access to electricity.

In its note published February 13, the French think tank presents photovoltaic solar energy as “a promising solution” to meet the increased electricity needs in sub-Saharan Africa. This note recalls the advantages of this sector – “whose potential remains largely under-exploited today” – while setting the conditions for effective development, through several proposals.

The Montaigne Institute notes that the power plants commissioned in Sub-Saharan Africa “continue to be essentially thermal or hydroelectric”, with an electricity production cost on average very high: “of the order of 0.20 to $ 0.50 / kWh “according to the African Development Bank (compared to an average of $ 0.10 / kWh worldwide).

At the same time, solar photovoltaic is developing “in multiple forms: lighting (solar streetlights or solar lanterns), individual kits (typically a power of a few watts), mini-power plants off-grid (a few kilowatts), industrial roofs in self-consumption (from the ten to the hundred kilowatts), large solar fields (from megawatts to tens of megawatts) “. Photovoltaic installations have the advantage of being fast to build in isolated areas.

In order to remove the obstacles to their large-scale development (in particular 5 to 50 MW of intermediate plants, “crucial to the successful electrification of the African continent”), the Institut Montaigne notes that it is necessary to reduce the the cost of financing these “very capital-intensive and small” projects. To this end, it recommends, among other things, “to standardize the contractual structure of projects in order to facilitate their aggregation and the securitization of the debts they generate, and therefore their financing”.

A bright future for Africa with Solar Energy

By | News | No Comments

More than half of the world’s people without access to electricity currently live in sub-Saharan Africa. According to Institut Montaigne, the number of people without access to electricity will continue to increase mechanically until 2025, when population growth is “faster than the rate at which people access electricity. “. And photovoltaic solar energy appears as an obvious and promising solution.

At the same time, solar photovoltaic is developing in multiple forms: lighting (solar street lights or solar lanterns) as at Estia Synergie; or industrial self-consumption roofs, solar energy solutions for agriculture.

 

The benefits of using solar energy

Solar energy has various advantages. It is part of renewable energies that produce electricity without raw material and without impact on the environment. But on top of that:

  • It can be installed in town or in the countryside. Indeed, the solar panels are simply attached to the roof.
  • Modular, solar energy can be used to meet a wide range of needs (power appliances, heating system, boiler …).
  • This free renewable energy source offers a convenient solution for obtaining electricity even in remote locations.
  • The operating cost of photovoltaic solar panels is low. In addition, they require little maintenance and are designed to withstand climatic hazards.
  • It is possible to resell the excess electricity you generate to amortize your investment.

Free trainings for villagers

By | News | No Comments

Free trainings for villagers
The Coffee-Cocoa Council, through its rural investment fund, financed the installation of 150 solar pumping and water treatment stations.

The goal is both social and economic.

Social because it allows easy access to drinking water; thus improving the health of the inhabitants and releasing women and children from the painful work of pumping.
Economical because it allows a counter-season irrigation by farmers.

In order to perpetuate these solar stations installed by Estia Synergie, free trainings are organized before and after the installations; thus ensuring the proper management and maintenance of stations.

Irrigation through solar pumping

By | News | No Comments

For irrigating crops or supplying drinking water in areas where the electricity grid is absent, such as Ivory Coast and Africa, pumping over the sun is often the most obvious solution.

Because, the progressive evolution, since 20 years, equipment and ranges of performances makes it possible today to consider solar pumping as a mature technology.

In some cases, no battery is required since electricity is not stored.

And it is indeed relatively easy to store water in a raised tank.

A solar irrigation system provides agricultural land with water quality that depends on the borehole or source used.

A solar pumping system over the sun must be sized according to the desired flow rate and the total nanometer height (HMT). Of course, the location of the project has a considerable impact on the size of the photovoltaic field.

Water treatment for your home with our UV and activated carbon filters

By | News | No Comments

The water is gradually polluting. Pipelines carry sludge, sand, earth. They drain metal particles, plastic. Bacterial proliferation or microorganisms develops. Everyday you are informed of these problems by the different media. If the water companies kill microbes and bacteria and guarantee the potability of water using chlorine, the water deteriorates more and more every day.

In order to have a treated and disinfected water available continuously at your home and thus overcome these pollution problems, ESTIA SYNERGIE proposes you its combination of UV and activated carbon filters which combines a pre-filtration of water with 25 microns to a filtration activated carbon and to UV sterilization of water.

 

Our UV filters and activated carbon for the treatment of water in your home is composed of a filtration system that aims to separate the water from solid particles (residues) by passing it through a system, which lets pass only liquids.

 

The 3 steps of water treatment with our UV and activated carbon filters

  • Anti-sediment pre-filtration at 25 microns: A cyclonic effect deployed by the centrifugal propeller precipitating the large particles in the bottom of the bowl followed by a fine sieve filtration adaptable to your needs (25μ) to rid the water of any particles in suspension.
  • Activated carbon filtration: An active charcoal treatment (granular) to treat water against unpleasant tastes and odors of water as well as pesticides and herbicides. A container containing this active carbon has been specially developed for reuse. The user will very easily change the charge of activated carbon by unscrewing the removable top cover.
  • UV disinfection: Sterilization of water by UV to guarantee the bacteriological quality of the water.

 

The benefits of our UV and activated carbon filters
