Overall, the main reason people choose DIY solar panel installation is the potential cost savings. There are two ways to save costs – buy the solar power kit and install it yourself or buy the kit and get a professional to install it. The cost savings are pretty substantial when you think of it – you might be able to reduce your purchase price of the solar panels from $4 per watt to $2 per watt. For a common 5 kW solar energy system, that could mean a cost savings of $10,000 right off the bat. That’s a 50% discount and seems pretty good, right? Well. . .maybe.
Easy to set up. Easy to use. Great for educational purposes. Can't be used without an household 120VAC electrical outlet available. This is a "grid-tied" solar kit, not for standalone applications. 230W is the "maximum" output power on a bright sunny day, but after conversion efficiency losses, this is only minimal output power, which won't make a big difference in saving electricity, not to mention it can only be used in the daytime. A bit pricey, but at only $2.69/watt not too shabby for a "starter kit" in solar energy.
I am a solar submersible well pump dealer/installer and just last week I ordered the 100 Watt HQST solar panel. When I received it i really felt and seen the top quality and make up of the panel. I was surprised because the panel was at 112 dollars and I expected it to be cheaply made. Not this one, this panel I will use mounted on a tripod to charge my RV batteries while out in the field. I will no longer need to trickle charge my battery using AC, I plan on leaving this panel outside all year round to keep my batteries fresh. I have no doubt that this solar panel will weather the elements nicely and without any problems. Get it now, just don't buy them all because I will be ordering some more soon. HQST 100 Watt 12 Volt Polycrystalline Solar Panel
The peak power rating, Wp, is the maximum output under standard test conditions (not the maximum possible output). Typical modules, which could measure approximately 1 m × 2 m or 3 ft 3 in × 6 ft 7 in, will be rated from as low as 75 W to as high as 350 W, depending on their efficiency. At the time of testing, the test modules are binned according to their test results, and a typical manufacturer might rate their modules in 5 W increments, and either rate them at +/- 3%, +/-5%, +3/-0% or +5/-0%.[18][19][20]
I’m working on getting the power company (which is owned by our small city) to change this policy, however, since they recently announced a goal of moving to 100% renewable power by 2030. I’m one of the few people who will make the switch even if it costs me MORE than coal-generated electricity, so I don’t actually care about the payback period. But most people require a financial incentive to make a change.
Since you are working hard to read this rather lengthy article, here is some entertainment. The ‘intermission’ if you like. So, put your feet up and enjoy the next picture: It’s a prime example of much that is wrong with the small wind world. The fact that an installer would even consider installing in a place like that. Customers that are too uninformed to know better (and their installer clearly is not interested in educating them). Turbine manufacturers that deliver standard towers that are much too short to be effective; this tower plus turbine is just 23 feet tall! Then there is the claim by the manufacturer (dutifully parroted by the installer) that this turbine will offset “up to 30%” of their electricity bill. The last one is not really a lie I suppose: If in reality it offsets just 2% of the owners bill, technically that still falls within that “up to 30%”…
In some states, you’re required to have certain certifications, or even be a licensed electrician, to legally wire solar panels. You should have experience and training in residential wiring, and knowledge about how local grid interconnection works. You’ll need to know how to purchase equipment that correctly matches your system requirements, including power conditioning equipment that’s critical for making the electricity produced by your solar panels compatible with the grid. You’ll also need meters, instrumentation, and safety equipment.
A Homeowner’s Guide to Solar Financing: Leases, Loans and PPAs – This guide from the Clean Energy States Alliance helps homeowners navigate the complex landscape of residential solar system financing. It describes three popular residential solar financing choices and explains the advantages and disadvantages of each, as well as how they compare to a direct cash purchase.
Square wave inverter is cheaper among the all but not suitable for all appliances.Modified Sine Wave output is also not suitable for certain appliances, particularly those with capacitive and electromagnetic devices such as: a fridge, microwave oven and most kinds of motors.Typically modified sine wave inverters work at lower efficiency than pure sine wave inverters.
Another thing to double-check on DSIRE is the installation requirement for any incentive programs you may apply for. Although I'm sure that the most Instructables users will opt for a DIY solar installation, you may not be qualified for state or local grants if you don't hire a government-approved contractor to do it for you. That said, a do-it-yourself solar project is both fun and rewarding! Check out the further reading for some advice on DIY solar.

Of course, this doesn’t take into account the fact that whoever built a power plant is now selling less kWh when the sun is shining, but that is the risk of that investment. The risk of installing rooftop solar is that the industry prevails over homeowner interests (some would say rights) and curtails your PV output instead of the power plant output.

There are various kind of Batteries. Car and bike batteries are designed for supplying short bursts of high current and then be recharged and are not designed for a deep discharge. But the solar battery is a deep-cycle lead-acid battery that allows for partial discharge and allows for deep slow discharge.Lead acid tubular battery is perfect for a solar system.
Next step is preparation, protection and painting of timber box (solar panel housing). Special hooks have to be attached to all four corners of the solar collector, so that it can be easily mounted on the wall (Fig. 16) using 10mm/0.4in screws (Fig. 17). Empty box is placed on the wall in order to precisely mark the spot for drilling the air inlet/exhaust.
Well, the Tumo-Int kit includes a wind generator, blades, charge controller, and other accessories like screws, nose cone, and etc. Further, the AC generator is a permanent magnetic triple-phase unit. Overall, it is one of the best residential wind turbine kits that you can try along with your existing solar array to add to energy production. Use the link above to buy a unit of the wind turbine.

At the back side I made a big circular hole just behind the inverter fan for fresh air suction from the outside. Later I covered the hole with plastic wire mesh. A few small holes are also made for inserting the wires from the solar panel, charge controller and inverter to the battery and AC output to the appliances. At both sides 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications on the inverter.
But alas, the inverter is what it is. It cannot be connected to another inverter to provide more power (though more expensive models can be), nor can it be configured to operate at a higher input voltage, should you ever get ambitious and change the system voltage to 24 or 48 volts. On the other hand, at $65, does it really matter? A slightly-used 800-watt AC power source that can draw power right off the battery is a handy accessory any vehicle would be proud to have tucked away next to the spare tire.
After the photons are transformed into electricity, the panels direct this energy to power the home. Some homes, those independent of the utility grid, must rely on battery storage to store energy, yet they may also have to rely on backup generators when there is too much demand on the size of the system. Many people use solar in tandem with the utility companies so that they have a convenient back-up during fluctuating periods of energy. This net metering partnership is a bit involved, but it has also been evolving to become more effective as more and more people choose solar to provide the bulk of electricity to power their homes.
