Solar panel kit: user manual, choice and price criteria

Why invest in a solar panel kit?

Your solar panels transform sunlight into electricity. By producing for free electricity of renewable origin, you offer 2 benefits: reduce CO2 emissions to combat global warming, use your electricity for personal consumption or total sale to EDF or to earn money.

To ensure that photovoltaic installation works, the solar panel kit must include: panels, inverters (which allows you to convert the current product into electricity that can be used on the national network), protective cables and sheaths, installation and connection, mandatory administrative procedures.

Reduce your environmental impact

The main electricity suppliers, still today, use nuclear and fossil fuels to produce their electricity (which sell you at a price that increases every year!). This production method poses several problems:

• Fossil fuels (coal, oil and natural gas) are limited resources. At the rhythm of their extraction, the global reserves will be exhausted between 40-60 years.
• The use of fossil fuels leads to greenhouse gas emissions that contribute to climate change.
• The nuclear industry generates radioactive waste, which expose to a risk of pollution from severe atmosphere and whose storage continues to be a problem.

In this context, the energy of renewable origin develop and photovoltaics allows you to act on your staircase. By investing in a solar panel kit, reduce the environmental impact and the campaign for a better future.

The solar kit for personal consumption to reduce electricity bills

The economic aspect of photovoltaics is a profit at least as much as the ecological aspect and an often more convincing topic. All the more in a context in which the price of electricity continues to increase … 1^era A way to earn money with a kit of solar panels: cars -consum. The principle is as follows:

1. Your solar panels produce electricity.

2. Use electricity to power electrical devices in your home: heating, lighting, appliances …

3 By selling excess electricity, you earn money.

Which profitability in the car -consum?

The car -content paid by the state, the savings on the invoices and the revenue from the sale of the surplus allow you to repay the price of the Solar Panel kit in ten years, depending on the sun from which you benefit and condition that you have paid the right price. The subsequent 15-20 years (the duration of the life of the solar panels is about 30 years), all the savings and profits made are a clear profit.

More and more of you use your car panel kit -with an excess sale. 3 reasons for this:

• A desire to increase autonomy.
• The annual increase in electricity prices. Every year, the electricity bill increases due to the increase in the KWH rate invoiced by your supplier. By reducing the use of the car network -consum, it improves your profitability every year.
• The drop in the price of the purchase of solar electricity by EDF or in the event of a whole sale.

The solar kit for total sale to generate income

2^th A way to earn money with a kit of solar panels: in full sale. Please note that you cannot eat electricity with this type of installation.

The principle:

1. Your solar panels produce electricity.

To find purchasing rates, read our item: photovoltaic purchasing rates

As mentioned above, the photovoltaic purchase rate decreases each quarter: in terms of profitability, the entire sale is no longer as interesting as at the beginning of the photovoltaic. One case, however, requires to consider selling in full: in the secondary residence, in which the electricity needs are reduced, the total sale is more profitable than the consumption of cars -ing -up (since the savings made on electricity bills do not compensate for the difference in the surplus purchase price that is less than total sale, 10 C € / kWh).

Choose your solar kit

Once you have chosen between cars -consium and in full sale, which kit of solar panels to buy? It is necessary to take into account the following criteria of choice: photovoltaic power, support and options.

Install maximum photovoltaic power for a faster efficiency of the investment

The power of the solar panel kit, expressed in KWC (Crête Kilowatt) determines the amount of electricity that you will produce: 1 kWc allows to produce from 800 to 1,400 kWh/year, depending on the sun.

The greater the power, the more electricity you produce. This means that you will save even more important in the car -condesses and that you earn more money for total sale. Of course, the price increases with power. But since some costs are set, the price of the Solar Panel kit is not directly proportional to photovoltaic power. Result: your profitability increases with the power of your solar panels. Therefore you have an economic interest in the choice of maximum photovoltaic power.

Be careful not to exceed 9 kWc (30 solar panels). In addition, the amount of the self -conscustration prize and the sale price for KWh decrease, your profitability is therefore less good.

Put your solar panels on the roof for better profitability

You have the choice between 3 types of support to install the solar panel kit:

1. The installation of roofs, superimposed or IAB: the panels are fixed on the roof of your home.

2. The Solve Obrier or lifts more Solier: a new building (garden shed, covered car, etc.) with a photovoltaic roof is built in your garden.

3. The land frame: the panels are installed on a support positioned in your garden.

In terms of profitability and aesthetic, the sun ground kit is the least interesting solution. The price of the Solar Refuge, insofar as it includes the costs of building a new building, is higher, which makes the profitability of your investment longer to reach. If you don’t need storage space or more shelter in your garden, you warmly recommend the installation of the roof solar panels kit. To reduce investment costs and therefore increase profitability, the Southly Solar Kit is the best option.

Solar kit: with or without battery?

In the consumption of cars -consum, you can buy an optional calendar battery. The battery allows you to store the excess electricity produced by the solar panel kit, to reincide it on the home electricity grid when the panels do not produce enough electricity. Thus earns autonomy.

Quula budget ropor?

The price of the solar panel kit depends mainly on the power and support of photovoltaic panels. Our online simulation tool allows you to quickly estimate your financial savings and earnings based on power, support and the region.

Some tips:

• Do not sacrifice photovoltaic power to reduce the price of your investment. More than the price, it is important to examine profitability. But a kit of cheap solar panels is rarely profitable.
• Remember to deduct the amount of state aid from the price. In 2019, you have financial assistance if you opt for the car -consum: the prize is currently € 0.29 for toilet for a 3000 toilet kit and more than the sun panel.
• If you don’t want/you cannot pay the price of the core of the solar panel kit, consider Loa.
