Calculating the profitability of your solar roof

Observations:

1. Revenue will be adjusted in accordance with the CPI for 25 years. RD 661/2007 guarantees the CPI minus 0.25% until 2012 and CPI minus 0.50% after 2012.
2. The calculation has been made with panels facing due south. Up to 20º of south-eastern or south-western deviation, the same values can be taken with reasonable accuracy. For 30º, the production will decrease around 3%. For larger deviations, seek assistance.
3. Check that your roof is not shaded by landscape elements such as trees or buildings. In this case, the numbers can vary considerably.
4. The total power to install must be adjusted to the size of the AC converter: 5, 10, 20 kW, etc.
5. VAT is not included in these figures.
6. All data are estimated. We recommend that you request a detailed estimate from our company.
