Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.: bypass the whole panel if you can ( one individual panel of several ) , or bypass that loop in that panel - car part rubber hose clamps

Q: If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?: Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.

Q: i have a small solar panel,the ones from a garden lamp that turns on at night-i think.what i was wondering is can i just connect the solar panel to a capacitor and then a light just to test?or do i need something to convert the solar energy to usable energy?and how do i tell if a capacitor is broken?: you don't need a capacitor. You can connect it to a light directly. Capacitors rarely break. You can check with an ohmeter.

Q: we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.: Solar Energy Is School! It's School To Go Solar!

Q: How do solar panels affect the property's energy resilience?: Solar panels can greatly increase a property's energy resilience by generating clean and renewable electricity on-site. By harnessing the power of the sun, solar panels provide a reliable source of energy that can offset or even eliminate the need for grid-supplied electricity. This reduces dependence on fossil fuels and the vulnerability to power outages or price fluctuations. Additionally, solar panels can often store excess energy in batteries, allowing for uninterrupted power supply during emergencies or blackouts. Overall, solar panels contribute to a more resilient and self-sufficient energy system for the property.

Q: Can solar panels be installed on water bodies or reservoirs?: Yes, solar panels can be installed on water bodies or reservoirs. This type of installation is known as floating solar or floating photovoltaic (PV) systems. By installing solar panels on water bodies, it maximizes the use of space and offers numerous benefits such as reducing water evaporation, increasing energy production due to the cooling effect of the water, and providing an opportunity to repurpose underutilized water surfaces for renewable energy generation.

Q: Can solar panels be installed on a streetlight?: Yes, solar panels can be installed on a streetlight. This allows the streetlight to be powered by solar energy, reducing reliance on the electrical grid and contributing to a more sustainable and cost-effective lighting solution.

Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.: Unless you're very rich, you won't be able to afford solar panels that can meet the average demand of a home. In the US, the average demand for a home is 920 kwh per month, which amounts to 3,833 Watt panels if you assume 8 hours of usable sunshine and don't take into account your location. At current installation rates that's easily a $9,65 project. If you assume a 25 year useful life, it amounts to a return of 3.3% per annum at 0 cents a kwh not counting the costs of repair, insurance, the inverter, any fees to the utility for net metering if any etc. You would be better off putting $9,65 into a mutual fund until better technology or government incentives came along, in some areas, the government subsidies can make it worth your while. Also, keep in mind that in many areas, the net metering arrangements only deducts the power you've generated from your bill so you would want to size the array to meet your base usage in order to get the most from your investments. So meeting your actual needs would result in a loss on the return as there will be months where your usage is less than your average. In theory, if you put $7,208.69 into a mutual fund expected to return 4.4% per annum then you could withdraw enough to pay each month's power bill for 25 years at $0.0 a kwh and therefore be self sufficient through financial means. You would get more mileage focusing on heating and hot water as heating and hot water is 75% of a home's energy use and can be addressed with lower cost technologies like passive solar and solar thermal panels. You have to put it into perspective, it's an investment and you want a return that's competitive with your investment opportunities.

Q: Can solar panels be used to power a space station?: Yes, solar panels can be used to power a space station. Solar panels convert sunlight directly into electricity, and in space, where there is no atmosphere to scatter or absorb sunlight, they can generate a significant amount of power. Several space stations, including the International Space Station (ISS), rely on solar panels to generate electricity for various systems and experiments.
