- Q: I am building a solar panel I have wired in series 36 .5 volt solar cells to produce 8 volts I have another panel that has 34 .5 volt solar cells to produce 7 volts. Any issues with wiring these 2 arrays in Parallel? I.E. would the smaller array take usable power away from the larger array?
- Hmmm (8v -7v)/ 0 ohms .... shakes head....
- Q: we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?
- A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
- Q: Can solar panels be installed on an agricultural greenhouse or nursery?
- Yes, solar panels can be installed on an agricultural greenhouse or nursery. In fact, it is a popular practice in many agricultural settings. Solar panels can provide renewable energy to power the greenhouse or nursery, reducing reliance on fossil fuels and lowering energy costs. Additionally, the panels can be mounted on the roof or ground around the facility, making efficient use of available space.
- Q: Can solar panels be used for satellite communication?
- Yes, solar panels can be used for satellite communication. Solar panels are commonly used in satellites to generate electricity from sunlight, which is then used to power various communication systems on board. The panels convert sunlight into electrical energy, which is stored in batteries and used to power the satellite's communication equipment, including transmitters, receivers, and antennas. This allows satellites to communicate with ground stations and other satellites in space, enabling various applications such as weather monitoring, navigation, and telecommunications.
- Q: Can solar panels be installed on swimming pool covers?
- Yes, solar panels can be installed on swimming pool covers. In fact, it is a popular choice for pool owners who want to harness solar energy to heat their pools while also conserving energy.
- Q: Can solar panels be used in conjunction with a backup generator?
- Yes, solar panels can be used in conjunction with a backup generator. This setup, known as a hybrid system, allows the solar panels to generate electricity during the day and excess power can be stored in batteries or fed back into the grid. When there is insufficient sunlight or high energy demand, the backup generator can kick in to provide electricity. This combination ensures a continuous power supply, making it a reliable and sustainable solution.
- Q: Can solar panels be installed on a condominium or apartment building?
- Yes, solar panels can be installed on a condominium or apartment building. However, it may require certain considerations such as the availability of suitable roof space, permissions from the building owners or management, and potential impact on other residents. Additionally, installation and maintenance costs may need to be shared among tenants or considered in the building's budget.
- Q: I was looking at thin flexible solar panels as solar panels 500w a option to upgrade a 20w solar panel I have permanently mounted to the roof of a home made camper van.Why I was thinking flexible is at just 2mm thin they can be glued down and being flexible they will follow the contour of the rounded shape of the roof of my camper (boxy standard solar panel spoils the lines a little)Another reason is no glass to brake when traveling on dirt tracks(though I am surprised mine hasn't broken yet after thousands of km on corrugated dirt roads). Finally there is a weight saving at only /3 the weight or less then a standard glass panel.There are different grades of flex PV some of the more expensive ones are very flexible with extremely thin backing at around .5mm The ones I was looking at are cheaper and at around 2mm with a thin flexible aluminum backing.$250 is about the going rate for 20w OKorder job. Below is a pic of a smaller one 60w or so.Has anyone had any experience with them?

- Q: Can solar panels be used for street lighting?
- Yes, solar panels can be used for street lighting. By harnessing the energy from the sun, solar panels can power street lights, eliminating the need for electricity from the grid and reducing carbon emissions. Solar-powered street lighting systems are increasingly being adopted as a sustainable and cost-effective solution for illuminating streets and public spaces.
- Q: I have just made my first dolar panel 20 watts, charges my 27TMX Trojan battery perfectly. Now I am thinking to build more solar panels for a grid tie installation at my house, maybe 5 panels would do it, is this safe?
