I have an Aerbus 28 ft that I would like to have a solar for my lights, TV, etc. What would be a good size watt? Is there one that can lay down and then put up once parked?

I’m looking to build a small home solar charging system, and I’d like to go to a store so that I can get advice on how to build it and what I can expect from the size of panel I create. Are there any good stores in the Portland Oregon area? Or a website that is very detailed? I have no prior knowledge about solar charging kits. And what I’ve found on google assumes you know what you’re doing…

Paul, the owner of this home, shows us the Solar Thermal Panels that heat the water in the home, and the Photovoltaic (PV) Panels that power the home. When it comes to the use of Solar Thermal panels , the US is significantly behind other countries. As Paul says, when you go to other countries such as Turkey, Israel and Japan, you see panoramas of homes with Solar Thermal panels. Yet here in the US we still burn Natural Gas 80% Efficient Water Heaters that have emission levels equal to that of a ’55 Chevy. The Solar Thermal panels on this home were installed on the main home’s roof and provide enough hot water for all domestic needs. The Solar PV Panels were installed on a separate studio located on the property, and they face a little bit west of due South. The system is composed of 24 PV panels, and adds up to 4.4 kW of power. This PV system along with the home’s Solar Thermal system zero out the home’s electric bill! Background: We took a trip to Sebastopol, California to tour the first LEED home in the world! The home was built from the ground up by Paul Rosen, Founder of North Bay Energy as well as a builder and sustainability consultant. Amazingly, the house is so energy efficient that the total annual utility cost is less that ! Skeptical? Well we were too, so Paul invited us to tour the home while he explained all the different design features.

Im making a solar panel for a project and Its output voltage will be around 16 volts at 1.05 A.
I charge my batteries at 13.4 volts, WHAT IS THE FINAL AMPERAGE???

Does anyone know a formula I can use??

Thanks a lot!!

I just bought a Harbor Freight solar panel kit and I am concerned about damage it might receive from weather conditions. It appears to have some sort of plastic over the solar cells.

I saw a cheap 12v portable solar panel on amazon and Im wondering if I can charge my laptop with it, the cell puts out 12v but my laptop uses 19v, can it still be used to charge my laptop (just more slowly) or will it not work at all?

We have LED at the output of 40 watts and is used for 10 hours giving us 400 Watts-hr of energy consumed.

Rechargable batteries needed are 12 V. 400/12 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34×3=100 Ah. So the battery needed 100 Ah

Now how do I select the solar panel which can charge this/these batteries? What should be its rating?

Is there will be any bad effect on solar panel or on battery or UPS (charger)?

Oh and I have another Physics question.. how do you calculate the final temperature of the water after half an hour, if he gave you the mass, the energy absorbed by the solar water heater and the initial temperature? Like, what formula do you use?

Thank you
