Solar Panel Project – Day 2

Thursday, January 21st, 2010 | Green Power

Day 1 of the solar panel project was really satisfying as we were able to install all of the solar panels in one day. At the end of the day we could see what we’d accomplished. Day 2 consisted of testing each of the 9 strings to make sure the were functioning properly. The plan was to get all of the strings jumpered and connected to the splicer box on the roof, but we ran out of cabling so that will have to be finished on Friday.

While we were on the roof, the electrician ran conduit from the roof penetration to the inverters (indoors). 3 SMA SunnyBoy inverters will do the job, but they take up way more wall space than I’d hoped. I have no idea where we will mount the inverters for future arrays. We went with three inverters to save money over buying one large inverter, but there is a space penalty.

Day 3 is a bit of a wash, as it’s raining, so nothing will happen on the roof. The electricians will be able connect the inverters to our panel. This is how the power gets into our system. We also wired the sunny boy webbox to the inverters which will enable us to monitor real time power production and see exactly how much power is generated by the system via a web browser.

Day 4 – assuming it’s sunny, we should be able to run the power from the splicer box to the inverters and crank it up. That’s the plan.
