Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:How many Watts of solar panels?
With an RV, you can find lithium bromide water chiller based refrigerators and air conditioner that run mostly on propane with just a little bit of electricity for a pump and fans. The oven, stove and heat, you can also run off propane. A Microwave is probably 750 watts but only operates for a few minutes at a time. You'll just have to go through everything item by item and figure out how many watts each one will draw and how long each will run per day to size your solar panel. Don't forget that the sun will only shine for a few hours each day. In general, for a camper, the target isn't to produce all the power you need but to slow down the drain on the battery bank to last till you get back onto the road where the engine can recharge the batteries. Keep in mind that the lithium bromide chiller systems only operate when stationary and level so some people opt for conventional electric systems just for convenience which sounds like what you're trying to do. Best way to figure out how much power each is drawing is by measuring it while in use. It may be worth it to put a meter on the battery bank and go camping one weekend with a generator or put a meter on the main circuit breaker panel and camp where power is provided, just to see what your typical use is. You're far better off running as much as possible from propane.
Q:Solar panel question?
i agree with Liz but have a diffrent point i think u have not calculated for the roof mounted solar panels i am giving youy a bsic understanding hope that will help you Roof Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to roof based mounting supports. Roof based mounting supports include: Pole mounts which are attached directly to the roof structure and may use additional rails for attaching the panel racking or frames. Ballasted footing mounts such as concrete or steel bases that use weight to secure the panel system in position and do not require through penetration. This mounting method allows for decommisison or relocation of solar panel systems with no impact on the roof structure.
Q: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.
Q:How do you charge a battery with a solar panel?
I okorder.com/... typical use page 8. These chips and the supporting capacitors should only cost a few £ (or $) but you will need to make a circuit board.
Q:What specification of solar panel do I need?
You will need, A battery to store the electricity from the solar panel. The amount of electricity from the panel varies up and down as things such as clouds, position of the sun, etc. reduce the amount of solar rays hitting the panel. The battery stores it all, the ups and downs, and sends it back out at a steady voltage so you can operate your p.c. / appliance. A minimum of 45 watts solar panel. 60 watts would be preferable. 45 watts will charge a battery in one day under ideal conditions. You turn the panel as the sun moves across the sky, no clouds. 60 watts will charge a battery in one day with out moving and regardless of clouds. A controler to prevent the electricity from flowing backwards from the battery to the solar panel when the sun goes behind a cloud or sets at night and the charge drops below the voltage of the battery. A good controller will tell you the charge condition of your battery so you know when it is too low to operate your p.c. safely. And finally an inverter with True Sine Wave capability to change the electricity from the battery into usuable power for your PC and other electronics. Not all inverters produce true sine wave electricity. The electricity has static in it and will make your pc screen jump around and not function as it should. New digital T.V.'s also require true sine wave electricity to operate. Go the extra cost and get the inverter with true sine wave and be happy with the way your p.c. functions. Figure out how many Watts your p.c. or appliance will draw. and match the Inverter to the need. Do not go too big, as they cost more and consume more of your stored electricity to operate. Save as much electricity as you can. You will be able to operate your p.c. appliance longer. When not using your p.c., you can operate your T.V. or other low watt appliance.
Q:Solar Panel watts needed?
Mimi: Solar Power is not really that economical, and has many other disadvantages as well. You did not specify much info in your question as to the size of the water or air pump. So let's make some assumptions to get you some numbers. ) Let's say the water and air pump are about HorsePower (HP). The HP pump , considering efficiency losses, will draw around ,000 Watts , or kW. 2) The 600 Watt LED Light is quite high --- they are usually much smaller lights 40 Watts or less. BTW --- these LED lights are very expensive light as well. Just so you are aware. Between the pump(s) ( maybe 000 to 400 Watts) and the 600 Watt light ----- and without knowing the specifics --- you are probably looking at around 2,000 Watts or 2 kW. A 2 kW Solar PV unit will run around $20,000. The PV unit will only run at full capacity during daylight hours. They usually average about 5 hours per day. So you will only be able to run your pump and LED Lights during the middle of the day --- maybe 0:00 AM to 5:00 PM. If you want to run the pump and lights after sundown, you will need battery back-up. The electric storage batteries will likely run about an extra $5,000. They will last about 5 years. If you decide this doesn't work out well --- you can stay with the local utility --- at $0.0 per kWh. It will cost you about $0.0 per hour to run the pump --- maybe 30 to 50 cents per day. It would cost you about 6 cents per hour to run your light. Maybe 30 or 40 cents per day. You could essentially run your pumps and light several hours each day --- all for about $ per day, or $365 per year. This sounds like a less costly alternative.
