FAQ

Do I only need solar panels to have energy in day and through the night?
Solar okorder.coms
Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.s
How big of a solar panel system would I need to get ?
I think if you have the land have a solar array on your land. Putting on the house could cause it to collapse! 400 kilowatts per week is a huge usage. Turn some stuff off and don't leave the entertainment stuff on standby. Fill empty spaces in your freezers with blocks of polystyrene and be sensible with usage.s
Solar panel placement idea?
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.s
Where is the best place to get an education/experience and job in the installation of solar panels? ?
The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.s
Generator for solar panels....?
Well the sun don't shine at night does it. Nor much on cloudy days. You either need a generator or a whole lot of batteries. The batteries are a pain to maintain, they're expensive to install and they have to be replaced periodically. Generator's probably a decent alternative. I'm sure most people just stay on the grid for their backup. Even better if you live in an area where you're allowed to sell back excess capacity. If you're looking to spend this kind of money anyway you could look at a household fuel cell that runs on natural gas. Awesome technology, though if you buy the unit all prebuilt and ready to go it's going to run you like 50,000 bucks.s
Why only Photo-Voltaic solar panels?
I agree with you John and for the same reason already put forth as a negative. Solar thermal is a more mature technology. This is the reason why I spent so much of the last winter studying it. I can be reasonably sure that what I learn will not be obsolete tomorrow with a new technological breakthrough. I built a solar addition/greenhouse to personally study the effects. So solar thermal panels are not the only way to go. With respect to electrical production. I have seen parabolic reflectors coupled to stirling engines and solar thermal trough heaters used to supplement steam generation for alternatively gas fired steam / electrical generation plants. On a trip to China over 4 years ago I noticed solar hot water vacuum tube collectors being sold in their local hardware and big box style stores. These were gravity fed package units intended to have the tank on the roof with a supplemental electric backup. The vacuum tube collectors seem to be one of the latest innovations in this technology. Using phase change materials temperatures in these panels can be produced in excess of 400 deg F. and they are useful in colder temps and on cloudy days. While they are still costly for many applications, I have been discussing the use of vacuum tube collectors with the owner of a laundrymat. Solar thermal will not pay back as well as conservation in many cases of older construction, but it currently seems better than photovoltaic panels. Solar thermal requires more understanding of systems and relative efficiencies. In one way solar thermal is more like the electric car while the internal combusion engine is like photovoltaic. The idea of producing electricity from the sun is a sexier idea. It is also more in line with our paridigm of: just producing lots of energy and to H with any conservation efforts. For that reason it seems to get more press.s
Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.s
