Is a battery a cost-effective option for my PV system?
Battery cost-effective option here we show an example of a 289 kW installation realised in 2022 with its own battery system. Whether or not to install batteries is an open question that depends in part. On the physical capacity available for the installation of photovoltaic panels and the energy consumption. Requirements of the project.
Since it is not always the most optimal and cost-effective solution. At KiDi-solar we carry out customised studies analysing each project individually. Verifying in each case whether or not the installation of batteries. For a photovoltaic installation is interesting or not.
If you have any questions, you can contact us through the various means we offer to find out more and get more information.
What battery capacity is suitable for solar panels?
In an apartment building, there are not many options where solar panels can be placed. Typically, these are a balcony or the outside of a wall. Alternatively, if you are sure that the safety of the mini power station. Will not be threatened, solar photovoltaic modules can be installed on the roof of a block of flats.
The minimum installation space and the difficulty of orienting the photomodules. To the sun significantly limit the number of batteries that can be installed for a flat. Four monocrystalline solar panels for a flat with a capacity. Of 340 W (1360 W in total) will produce 9.5 kW of electricity. In 7 hours of operation on a bright sunny day.
For a 12V system, the solar panel battery capacity table is as follows:
50W 20-40 Ah
100 W 50-70 Ah
150 W 70-100 Ah
200 W 100-130 Ah
300 W 150-250 Ah
340 W 200-280 AhFor 4 monocrystalline 340 W panels you will need 4, 12V – 280 Ah gel batteries.
