Q: I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?: You okorder /

Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?: your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there

Q: Can solar panels be used for agricultural purposes?: Yes, solar panels can be used for agricultural purposes. They can provide power for various agricultural operations such as irrigation systems, livestock watering, grain drying, and greenhouse heating. Additionally, solar panels can help farmers reduce energy costs and dependence on fossil fuels, making them a sustainable and environmentally friendly solution for the agricultural sector.

Q: How do solar panels affect the roof's lifespan?: Solar panels can actually extend the lifespan of a roof. They act as a protective layer, shielding the roof from harsh weather conditions and reducing direct exposure to sunlight. This helps to prevent deterioration and can ultimately prolong the roof's lifespan.

Q: Can solar panels be installed in areas with high pollution levels?: Yes, solar panels can be installed in areas with high pollution levels. While pollution can reduce the efficiency of solar panels to some extent by blocking sunlight, they can still generate electricity even under such conditions. Regular maintenance and cleaning can help mitigate the impact of pollution on the performance of solar panels, making them a viable option even in areas with high pollution levels. Additionally, installing solar panels can help combat pollution by promoting the use of clean, renewable energy sources.

Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?: I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}

Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?: No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)

Q: can solar panels have glass between the panels and the sun?: As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.

Q: How do solar panels affect the insurance premiums of a property?: Solar panels can potentially affect insurance premiums of a property. While it varies depending on the insurance provider and region, installing solar panels may increase the overall value of a property, which could result in a higher replacement cost in case of damage or loss. However, some insurance companies offer specialized policies or discounts for homes with solar panels due to their positive impact on energy efficiency and reduced environmental risks. It is best to consult with insurance providers to understand their specific policies and how solar panels may impact premiums.

Q: Can solar panels be used in areas with high levels of air humidity or moisture?: Yes, solar panels can be used in areas with high levels of air humidity or moisture. However, it is important to note that excessive moisture can affect the performance of solar panels over time. Therefore, proper installation, regular maintenance, and periodic cleaning are crucial to ensure their efficiency and longevity in such environments.
