FAQ1
We have organized several common questions for our clients，may help you sincerely：
1.What price for each watt?
It depends on the quantity, delivery date and payment terms,
2.How do you pack your products?
We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.
- Q: Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.
- I'm in the California Foothills and the island of Mindanao... I have both solar panels (electric and water heating) and a single wind-generator since 2000. We actually sell power to PGE in California and are self-sufficient in Mindanao. NOW, I'm confused with YOUR math... you say the Rep. suggests a monthly savings of $35 (25% of $40) which would be $420 / year. If materials / installation are $8,000 less $2000 tax-credit: it would take 35 years to pay off $6,000 at $420 / year. 980 Kwh/ mo is some pretty heavy usage... I'd suggest trying to reduce that. CFT's, lowering your AC setting, no lights if NOT in room, un-plugging stand-by appliances, and upgrading insulation. At our 2000 sq ft California RANCH we only burn 400 Kwh per month, and that includes an 800 sq ft barn (admittedly we heat with a wood-stove). We have 5, Sanyo 200 watt panels (3kw total) and generate an avg 900 kwh / month. SO, we're selling BACK almost 500 kwh mo. to the grid on the photo-cells alone. The kw wind generator averages another 20 kwh / month. I THINK the company YOU are working with is selling the EXCESS electrical-power back to the power-company behind your back !! GOOD LUCK
- Q: Can solar panels be used off-grid?
- Yes, solar panels can be used off-grid. Off-grid solar systems are designed to generate and store electricity in batteries for use in locations without access to a utility power grid. This allows for self-sufficiency and independence from traditional power sources.
- Q: If a solar panel (using 36 3x6 solar cells) puts out 60 watts, how many panels would I need (for a house) if I use a max of 2300 kWh in a month? I checked my electric usage for the past 2 years and the kWh is usually lower but I wanted to use the most kWh used (2300) for my question. Thanks!
- One key piece of information missing is the average number of peak sun hours per day. This will vary by location. It is latitude, regional weather, and site shading must be considered. Another consideration is the loses. The 60 watt solar panel is a DC voltage. The 2300 kWh is for the AC power consumed. There are loses in the inverter to change the electricity from DC to AC. There are also loses for wire resistance, soiling of the panels, wire resistance, etc. To work out an example of the math, I'll use 5 peak sun hours and a total efficiency of 80%. The math can be worked out as a single formula but I'll break it into steps for you. (2300 kwh/month)(month/30.4 days) = 75.65 kWh/day (60 W)(5 psh)(80%) = 240 Wh/day = 0.24 kWh/day/panel # of panels needed = Energy use / Energy generated (75.65 kWh/day) / (0.24 kWh/day/panel) = 36 panels.
- Q: Mono-crystalline or poly-crystalline solar panel?
- All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
- Q: My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- If you only use it for demonstrational . 75W-00W small solar panels would be that you are looking for, you can use it heat up the water. With simple guide you can do it yourself easily and cheaply.
- Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
- Yes its true! electric bills are getting higher and higher. That's why a lot of people or businesses turn to alternative sources of energy. It is a little cheaper but can still provide the same level of energy. It is even good for the environment. If you are considering a switch for your energy provider, learn first about the different alternative sources of energy at businessswitchonline .uk. It might be helpful in making up your decision. Also, solar panels will depend on how large your house is or if it is really qualified for solar energy. You need an energy provider to have an evaluation of your house before you set up a solar panel.
- Q: Can solar panels work in the shade?
- YES. They work in direct proportion to the amount of light falling on the surface, regardless of the source of the light. In the shade simply means reflected light instead of direct sunlight, falls on the panel, with that much less output. The earth has an albedo of about 8, which meas about 8% of the light falling on the earth is reflected. The moon has an albedo of 2, which means 2% is reflected, which is why shadows on the moon are not jet black as you might expect in an airless place. The atmosphere of the earth is why shadows are lit as they are. The conspiracy theorists thought they had something to prove the moon landings were faked with the shadows not being black. They neglected to account for reflected light from surrounding sunlit objects scattering light the shadows.
- Q: I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?
- I didn't research this. I do know that you must install them on the side or area of the roof that receives the most Sun all day. You can get information at stores like Lowes or HomeDepot.
- Q: Can solar panels be installed on a theater or entertainment venue?
- Yes, solar panels can be installed on a theater or entertainment venue. In fact, many theaters and entertainment venues have embraced solar energy as a sustainable and cost-effective solution for their energy needs. Solar panels can be installed on the roof or any available open space surrounding the building, generating clean and renewable electricity to power the venue's operations. This not only helps reduce their carbon footprint but also saves on energy costs in the long run.
- Q: I am heading to Nepal and do not want to lose power on my cameras but they can only be charged via quot;plugging inquot;. A USB connection does not work. Looking for a solar panel to clip to my bag or carry that I can plug in the charger as if plugging in to wall outlet. Thanks.
- Solar panels require a charge converter before it can be used by an AC source. There is no direct solar panel with built in charge converters that I know of because, when purchasing panels, you must purchase the wattage requirements of the job (this can be several panels linked), and a charge converter that will handle the <? panels required. A chain of stores up here in Canada have a portable battery pack that has a solar panel to increase its charge capacity or duration, but its not something you would want to lug around for long periods of time, because is weights in about 3 lbs.
