%26quot;STEP 1. SOLAR PANELS: or PV panels are the key to a hybrid system., converting the sun’s beams into electricity that we can use in the home. They come in many different sizes, shapes, power ranges and costs. We will focus on a 12v 50watt (4amp) panel, measuring appx 4 sq. ft. with a price range from $300-$500.

%26quot;Retrieve a typical winter electric bill. You won’t need a summer bill, because by building a system that runs in winter, it’ll be proven for summer use where days are longer. Divide the total KWH (Kilowatt Hours) on the bill by 30 (giving you your Kilowatt Hour per day, or KWH/d consumption amount), now divide that by 10 (or the total average winter day hours in your area)(giving you KWH/h), now multiple that by 1000 (converting KWH/h to WH/h or watts).%26quot;
%26quot;Now that we know how many watts your systems requires, we need to know how many panels to use, along with an adequate- sized controller. For simplicity reasons, let’s use a typical 50w solar panel. We will divide your final “system requirement” results from above by 50 to tell us how many panels you%26#039;ll need (hourly winter consumption watts / 50).%26quot;
%26quot;NOTE: Size (watts and feet) of panels is a personal choice and isn’t determined by any system requirements.
Mount panel/s flat (0 degree) facing south (if located in the north hemisphere). With a multimeter, measure the incoming amps (via pos cable to battery), slowly raise the top edge until the amps peak on your meter. Secure.%26quot;
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at http://www.agua-luna.com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.
