Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.: outside is going to be much better. You can't tell but glass is actully opaque to many ranges of 'light'. If you look at advertising for windows you may see claims to reduce sun fading of your carpet/ furniture. That is because the glass blocks UV. Solar panels get some of their energy from UV light. Also some windows are engineered to block IR to help insulate better when the house is cooler than the outside. Again, solar panels get some of their energy from light in the infrared range. And finally if you're charging batteries the 'off angle time' is still important. The amount of light absorbed is pretty closely related to the cosine of the angle that the sun is 'off' of the direct. so when the sun is 45 degrees off of perpendicular the panels still get cos45 =.707 or about 70% of the available energy. (In practice it's a little less than that because not as much energy gets to the panel to be absorbed as at midday). But anyway, you can figure two hours of morning or late afternoon sun will give you as much energy as hour of midday sun. So if the panel is inside, you miss out on that available energy.

Q: i am trying to figure out how many solar panels can be placed on one acre of land and how much they cost to install: There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Q: I'm part of the Sustainability group at school, the school principal is a d**k and doesn't care about the environment, he only cares about money.Me and the group will be talking in front of him and the school council (the people in-charge of the school's money) To convince them to put solar panels on the school roofs.I know that it definitely will help the school save on electricity bills, but it WILL cost a lot of money to put them in.In the end we just wanna reduce carbon emissions!HELP :): When okorder / Good luck but the best way to win is to find a way to get it done and then they can't say no.

Q: I am looking to get some solar panels for my home to just power a few lights, a fan or two. I have a generator but I want that only to power the fridge and maybe some other small stuff for convenience.But mainly want the solar panels for the lights and fans. Any one have an idea of how about I go to figuring this all out? Should I call a contractor or anything?: depends on what light bulbs you have in watts.depends on how many you want on. for the power equation you take P which equals watts x I which equals amps and E which equals volts and you multiply the amps and the volts together to get the watts which the solar panel is generating. for example if you had 7 60 watt light bulbs you would need 420 watts generated. which if you got 50 watt panels each you would need 9 panels. and for what your talking about if you want the stuff to work when the power goes out you are going to need an inverter. not to be confused with a grid ti inverter. and a few batteries i recommend deep cycle batteries that are meant for solar panels. depends on what fan you have.

Q: Can solar panels be installed in areas with heavy snowfall?: Yes, solar panels can be installed in areas with heavy snowfall. However, it is important to consider certain factors such as the angle of the panels, their orientation, and regular maintenance. Proper installation and tilt angles can help reduce snow buildup, and occasionally clearing the snow off the panels may be necessary to ensure optimal energy production. Additionally, advancements in solar technology have made panels more resilient and efficient in colder climates, allowing them to generate electricity even in snowy conditions.

Q: Can solar panels be installed on south-facing windows?: Yes, solar panels can be installed on south-facing windows, as long as there is enough sunlight exposure throughout the day. South-facing windows tend to receive the most sunlight, making them a suitable location for solar panel installation. However, it is important to consider any potential obstructions or shading that may affect the panel's efficiency.

Q: Okay so.. if light deflect the light of the sun and black absorbs it, then aren't solar panels just absorbing more light, sun and heat into our atmosphere? Wouldn't this lead to an increase in global warming? Shouldn't solar panals be white? No rude answers please.: If the panels are deployed at outer surface of atmosphere then white will reflect the sun light to outer space. If the panels are deployed at earth surface, inside the atmosphere, most of the reflected light will be bounced back to earth by the atmosphere. For the solar panels we are talking about, they need to be dark color to absorb light and turn into electricity.

Q: What is the lifespan of solar panel batteries?: The lifespan of solar panel batteries can vary depending on various factors such as the type and quality of the battery, usage patterns, and maintenance. On average, solar panel batteries generally last between 5 to 15 years. However, with proper care and regular maintenance, some high-quality batteries can last up to 20 years or more.

Q: Can solar panels be installed on a pole or ground mount?: Yes, solar panels can be installed on both poles and ground mounts. Pole-mounted solar panels are typically used in situations where there is limited space or when the panels need to be elevated for better sunlight exposure. Ground-mounted solar panels are commonly used in larger installations or when there is ample available land. Both options offer flexibility in placement and can effectively harness solar energy.

Q: Can solar panels be installed on a balcony or terrace?: Yes, solar panels can be installed on a balcony or terrace. However, it is important to consider the structural integrity and load-bearing capacity of the balcony or terrace before installation. Additionally, the orientation and shading of the area should be evaluated to ensure maximum sunlight exposure for efficient energy generation. Consulting with a professional solar installer is recommended to determine the feasibility and safety of installing solar panels in this specific location.
