Information about your past electric usage

On your power bill you will see a breakdown of electricity used for that month. We need to record the amount of energy used in units of kwh. This information is important because it will help determine how large your solar power system should be and it will also help analyze the finacial implications. It is recommended that at a minimum, you enter two months worth of data, one for the summer and one for the winter. Leave values blank that you do not have, do not enter zero.

For the next set of questions, you need to roughly decide where you would put a solar panel array. If you choose to mount your array on the roof you need to decide which part of the roof. Please note that the ideal location is a shade free southern exposure.

Shading

How much shading do you experience from the sun where you want to put solar panels? Shading is a critical factor in determining your system performance and it varies during the year. In the very simple case, estimate during the course of the YEAR the percentage of non-sun coverage. In the ideal case of no shading, enter a value of 0.
