How does it work?

It’s quite simple really!

When you place an order you specify your location, how much electricity you need per day and the number of rainy days the off-grid system should work well.

I then send you my calculated results in an e-mail, stating how you can put together your off-grid system. The solar panel power is given in watts and the battery energy in kWh.

Example 1:

Kiev, Ukraine. An off-grid system which should provide 1 kWh of electricity every day during April and May. It should be able to still work during 3 days of rain, if they are followed by 2 average days.

Result: 500 Watts solar panels, 4.2 kWh lead-acid batteries

Motivation: The graphs show a simulation of the off-grid system’s performance for the given rainy and average days.

Example 2:

Lisbon, Portugal. An off-grid system which should provide 600 Wh of electricity every day during August and September. It should be able to still work during 4 days of rain, if they are followed by 3 average days.

Result: 250 Watts solar panels, 3 kWh lead-acid batteries

Motivation: The graphs show a simulation of the off-grid system’s performance for the given rainy and average days.
