How many solar panels do I need?
We help you!
Determining how many panels you need and how much electricity you want to produce can be difficult. If you need help with this, we can always help you. We always ask for your energy bill, so that we can see what your average consumption is.
Don’t think too big
We recommend choosing a system related to your consumption. Despite the fact that the excess electricity produced can be injected into the grid (with reimbursement), the payback time is shorter when the system is configured for your average power consumption.
If you think you will use more electricity in the future (think of extra air conditioners, heat pump, pool heating, etc.), we would advise a more powerful inverter. A stronger inverter means that you will be able to extend with more solar panels in the future.
Average consumption in Spain
The average electricity consumption of a Spanish home without a swimming pool is approximately 8 kWh per 24 hours. This is an average of apartments and villas, so this can vary considerably with your situation. Therefore always consult your electricity bill or contact us.
Your pool always uses electricity
If you are not in your home in Spain all year round, you have a low electricity consumption for a few months per year. However, your pool pump is a large consumer in your home and must run all year round. A small solar panel system can therefore also be an interesting investment for people that are only in Spain for a couple of months per year. It is also possible to replace your swimming pool pump with a solar swimming pool pump. The solar-powered pool pump keeps your pool clean throughout the year through three or four solar panels which are directly connected to the direct-current solar pool pump. In addition to the fact that your swimming pool pump no longer uses electricity, your swimming pool will also be filtered considerably longer. For more information, contact us or visit our website.
Average yield in Spain
To calculate the production of solar panels quickly and easily, you can use the following calculation. Please note, this calculation applies only to the Costa Blanca region and gives your the average production. In summer the production will be higher, and in winter it will be lower.
10 solar panels of 400W = 4 kWp
4 kW x 0,8 (efficiency factor) = 3,2 kW
3,2 kW x 6 = 19,2 kWh per day
19,2 kWh x 365 days = approx. 7.000 kWh per year
