Just finished the build on this for the purpose of emergency power for computer network systems out in the field when I lose a main inverter. This is for use on a commercial solar site, but could easily be used on a home or any other hybrid application as long as you add your own panels. On my...

https://www.hukseflux.com/products/pyranometers-solar-radiation-sensors/pyranometers/sr30-m2-d1-pyranometer These are what we use on the site for data feedback. Now these are expensive and meant for commercial operations like I have. We collect the date from several of these on site and some...

On my solar farm we run a single axis tracking system, made by game change. We have an irradiance detector on a couple of shafts that detect the ideal sun angle at any given time. The benefit to this compared to an algorithm is sometimes the ideal angle to get the most irradiance isn't 100%...

I really do not want to mess around with batteries, I want to use the grid as my battery. Without the batteries all power I use when the sun goes down would come off the grid, so basically with solar my power would be free while everyone is at work and not at home to use it. I could care less...

Tried to use Shine Solar and had a really bad and stressful 3 months of not getting anything. Made a whole lot of promises verbally to get me to sign the contract. Later came back and tried to tell me what they were going to provide that didn't include anything I was promised verbally. Had to...

Just moved to Arkansas a year ago. All my associates are located in Michigan. I could probably have one of them whip something up, so that really isn't the problem. I'm not sure that they would even accept a PE stamp, but the guys I know that carry them all carry them for the state of...

Sorry about the rant, but it is just ridiculous. Right now trying to deal with Entergy Arkansas for approval to install a grid tied system. Small in the big scheme of things at 5.3 kW. The problem is the paperwork wants a drawing that is not a problem on the face of it, but the guy I talked...

I don't have Enphase inverters but researched them extensively and decided to go with something else as all their equipment seemed to follow the same principles Apple uses. Everything is proprietary and if you want to connect anything else to it, it has to be bought through them at a premium...

For most residential you could probably get away with a good pair of goat skin gloves as I think they are good for 120 VAC and 150 VDC, but they can't have any damage. Once you go above that and up to 500 V you should start wearing class 00 rubber gloves and I always use protectors over my...

I believe the national electric code is to upgrade the wire by 1 size for every 100 feet of run.

Be glad you are working residential solar and not commercial. DC voltages on my commercial 180 MW solar farm get up to 1500 volts pushing 200 Amps. That would fry the heart like an egg in a blast furnace. All techs on site are required to wear class 0 gloves when handling any PV wiring.

I currently manage and maintain a 180 MW utility scale solar farm. I am now branching out and looking to install residential solar on my own home. Looking to build a small 5 kW system at first, but looking to make sure it can easily be expanded on in the future. The electrical part is pretty...
