Solar shingles are smaller than panels and their wattage is lower as a result. On the other hand if they are 330w panels only 21 are needed.

Garrison remarked gas oil and electric aren t giving you a payback. Given your additional information from your comments that you ise 400kwh in summer and 1000kwh in winter amd that you are in africa a little vague.

The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. Solar panels are graded by how much power they use. One solar panel produces about 1 24 kwh per day. I installed my most recent system about 2ye.

Any shading on the roof reduces the amount of production garrison warns.
