Q:Are there any disadvantages to using solar panels?

Yes, there are a few disadvantages to using solar panels. Firstly, the initial installation cost of solar panels can be quite high, which may deter some people from adopting this technology. Additionally, solar panels require a significant amount of space for installation, making them impractical for individuals with limited rooftop or land availability. Furthermore, solar panels are dependent on sunlight, so their efficiency can be affected by factors such as weather conditions and geographical location. Finally, the production process of solar panels involves the use of certain chemicals and materials that can have negative environmental impacts if not properly managed.

Q:Has anyone had any experience building their own solar panels for home use? I have seen on the news lately that people are utilizing solar panels to power their hot water heaters to save on their power bill.

a solar hot water heater is not a solar panel that makes electricity that runs your hot water heater.....it is merely a long tube or pipe, bent back on itself so there,s, say 00 feet in a 2foot by 4 foot space; it's in a framework and under a sheet of glass or plastic; You put out in the sun and it captures heat.....ever notice how hot the water is coming out a garden hose that has been left out in the sun in summer? Same idea.. we have used them here in the islands for years and they work great. Even up north, a solar hot water heater that preheats the water before it goes to a traditional water heater should work fine.

Q:Can solar panels be used in urban areas with limited space?

Yes, solar panels can definitely be used in urban areas with limited space. There are various innovative solutions available such as rooftop solar panels, solar panels integrated into building facades, and even solar panels installed on vertical structures like lamp posts or noise barriers. These compact and versatile options allow urban areas to harness solar energy efficiently, even with limited space.

Q:Are solar Panels worth it, Do they really quot;save moneyon electricity?

“Where you have good (sunlight) and access to financing and a combination of federal and state incentives, you have a number of markets around the country that are very vibrant, and it’s very cost-effective with financial paybacks in the order of five and 0 years,” said Robert Margolis, a senior energy analyst at National Renewable Energy Laboratory (NREL).

Q:i have a small solar panel,the ones from a garden lamp that turns on at night-i think.what i was wondering is can i just connect the solar panel to a capacitor and then a light just to test?or do i need something to convert the solar energy to usable energy?and how do i tell if a capacitor is broken?

Most solar panels convert the energy collect from the sun directly into usable DC current. So no, you do not need a capacitor to test a light if you are in sunlight. You will need a capacitor or rechargeable battery if you plan on testing the solar panel away from a light source after the capacitor or battery has charged. Solar panels cannot store electricity.

Q:Can solar panels be installed on educational institutions?

Yes, solar panels can be installed on educational institutions.

Q:How much space is needed to install solar panels?

The amount of space required to install solar panels depends on various factors such as the type of solar panels, their efficiency, and the energy needs of the property. Generally, a typical rooftop solar panel system requires about 100-400 square feet of space for every kilowatt (kW) of solar panels. Additionally, open areas or ground-mounted systems may require more substantial space. It is recommended to consult with a solar installation professional who can assess the specific requirements based on the location and energy goals.

Q:If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?

75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.

Q:Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.

There okorder From panels, to inverters, to controllers, etc. Just look in their alternative energy section. If you happen to have aboutt 30,000 dollars to drop on the installation and you plan to live their more than 0 years, talk to your power company and they can set you up completely.

Q:Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?

If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
