This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
What are you going to power with your 260w solar panels? Tools? They generally use more than 260w. The panels will generate electricity. The problem is that your tools likely don't use DC. And if you're asking here, it's not likely that you have the background to hook everything up correctly. You'd need both batteries and a pretty good sized inverter.
Solar panels are designed to be durable and withstand various weather conditions, including hail. They are made with tempered glass that is highly resistant to impact, ensuring that hailstones won't damage the panels. Additionally, the panels undergo rigorous testing to ensure they can withstand extreme weather conditions, such as strong winds and heavy snow. The frame surrounding the panels also provides stability and protection.
I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
I've recently started a project to help my store become more green and I need to get some estimates from businesses and if all goes according to plan we will have some panels on our roof and some other measures that I've written into my proposal. Any help is welcome. Just so you know it's a large grocery store in a corporate chain and I've been approved to do all the research, just no promises of payment.

i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.

i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
If all things are equal buy local. If you are building for a LEED project then choose a manufacture within 500 miles. Another reason to choose a local panel is that if things go wrong there is a better chance of a satisfactory resolution. A no name knockoff from overseas might prove to be difficult to find a few years down the road. One good place to check is the Go Solar California website. They have proof of performance testing on hundreds of panels.
The amount of energy a solar panel can generate depends on several factors, including the size and efficiency of the panel, the amount of sunlight it receives, and the geographical location. On average, a standard residential solar panel can generate between 250 to 400 watts of power per hour, or around 2 to 4 kilowatt-hours per day. However, larger commercial or utility-scale solar panels can generate much higher amounts of energy, ranging from several kilowatts to several megawatts.
