To find the answer to number 3, you need to find out how many watts one square meter of panel absorbs.
If 8 collects 8,160 watts of power then that means 1 collects 1,020.
Now we know what 1 collects, you multiply it by 12 to find out how much power 12 square meters of solar panels absorb.
1,020 x 12 = 12,240.
12 Solar Panels absorb 12,240 WATTS. Do not forget to include WATTS at the end of your answer.
