Once again, our professional installers have traveled to Seville to install an 8 Kw self-consumption solar kit in a home. This has been motivated by our client's own interest in considerably reducing their electricity bill, since everything that the solar panels produce during daylight hours will be injected into their home and will power their electrical appliances for free.
These installations are characterized in that the use of solar batteries is not necessary. The objective is to reduce and not eliminate the consumption of the network completely. So much so, that we can notice how our electricity bill is reduced by up to 75% of each monthly payment.
This solar kit does not need permits from any electricity company to be installed, since its "zero discharge" system to the electricity grid does not allow anything to be dumped, and in this way we save ourselves any legal paperwork
As we can see, the installation has 28 panels of 330W. Doing the calculations for a winter day with 4 hours of sunshine, this solar kit is capable of producing an average of 9,240 w/h and about 36,960 w/day. In summer, logically, these figures increase, reaching a production of 64,680 w/day.
They were placed on a solar panel structure on the roof. Our installers placed them flat, as the client requested, to avoid viewing them from the outside, although seeking maximum photovoltaic exposure.
An 8000W 220V single phase zero discharge grid injection inverter was used, with an input voltage range of 100-500 Vdc. This has a limiter to reduce the output power according to the real consumption of the house, thus completely avoiding overflows to the public network. Through the MPPT function it provides maximum efficiency of the solar panels.
The solar inverter was installed inside the house, protected from extreme temperatures and humidity that could negatively influence its correct operation.
The solar kit includes all the necessary material for the correct operation of the installation (solar panel structure, fuses, wiring, circuit breaker, etc.)
It is recommended that the kit be installed by a photovoltaic professional, since it consists of devices that require special handling and knowledge for optimal system configuration.
If you are thinking of buying a grid-injection solar kit like this or any other, contact us and we will give you a tailored quote without obligation based on the needs of your home and consumption.
