1) The calculations are taking the deterioration of the solar panel and rechargeable batteries already into account. In case of NiMH batteries only use low self discharge (LSD) batteries with a capacity of at least 2000mAh (We recommend GP-Recyko).
2) The 60° slope of our 1Wp solar panel is an optimum to get through the darkest months in Northern Europe. Outside the tropics you need to face the panel to the equator, inside the tropics you need the face the panel eastwards (Azimuth = -90º) or westwards (Azimuth = +90º).
3) You can use the EU-PVGIS tool to determine the yearly and monthly in-plane irridation in kWh/m2 at the optimum Azimuth for our 60º sloped panel in your region. If your region is outside the data coverage, choose a matching GPS latitude in side the data covered area.

In the EU-PVGIS tool:
- Double click your location in the Map
- Specify the slope of your solar panel (60º for our integrated 1Wp panel)
- Specify the best Azimuth for your situation/region
- Click the 'Visualize results'-button
- Note the 'Yearly in-plane irradiation'-value
- Click the 'Radiation'-button.
- Calculated the monthly average over the 3 darkest months
