Q:im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?: It is tough to answer that question since efficiency is something u pay for thus the price can varies greatly but here is a few web sites you could check out and most would probably be happy to help with any info if you contacted them and the last one has allot of other info that could help like handling waste and water usage in this home

Q:Got a quote for about $K today for solar panels to save me about $00 a month on my electric bill. I was just wondering if anyone had successfully bought and installed their own and how it worked for you?: If you're in San Francisco, then the price of labor is going to be high. It's still legal to install your own, but you'll need to pull a permit, and get an inspection. If you hunt around on the PGE website, they'll guide you as to requirements. Aside from a standing-seam metal roof, the easiest install would be over asphalt shingle. As with any roof penetration, flashing and sealing the holes is critical.

Q:Can solar panels be installed on a rental property?: Yes, solar panels can be installed on a rental property. However, it ultimately depends on the landlord's consent and willingness to invest in the installation.

Q:I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?: It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.

Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?: I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..

Q:Can solar panels be installed on restaurants or hotels?: Yes, solar panels can be installed on restaurants or hotels. In fact, many restaurants and hotels have been adopting solar energy as a sustainable and cost-effective solution to reduce their carbon footprint and electricity bills. Installing solar panels on rooftops or in parking lots can generate clean energy, helping these establishments become more environmentally friendly while also saving money on electricity expenses.

Q:Can solar panels be used in areas with frequent power outages?: Yes, solar panels can be used in areas with frequent power outages. Solar panels generate electricity from sunlight, which means they can continue to produce power even during power outages. By installing battery storage systems, the excess energy generated during the daytime can be stored and used during periods of low sunlight or power outages. This allows solar panels to provide a reliable source of electricity in areas with frequent power outages.

Q:What is the difference between on-grid and off-grid solar systems?: The main difference between on-grid and off-grid solar systems lies in their connection to the traditional electrical grid. On-grid solar systems are connected to the grid, allowing them to both generate and consume electricity from the grid when needed. They can also feed excess electricity back into the grid, earning credits or compensation through net metering. In contrast, off-grid solar systems are not connected to the grid and operate independently, relying solely on solar energy to generate and store electricity in batteries for use when the sun is not shining. Off-grid systems are typically used in remote areas where grid connection is not available or for those seeking complete energy independence.

Q:Can solar panels be installed on a gas station or fueling facility?: Yes, solar panels can be installed on a gas station or fueling facility. In fact, many gas stations and fueling facilities are increasingly adopting solar power as a means to reduce their carbon footprint and save on energy costs. These solar panels can be installed on rooftops, canopies, or even as carports, making them a versatile and effective solution for powering these energy-intensive facilities.

Q:I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?: A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
