We currently have16 solar panels and 12 batteries with a 28kW system. We have a backup generator for cloudy or snowy days. I would like to see us get a wind turbine for nighttime power production. However, I do not want a 100 ft tower in my yard. Oh yeah, we are 14 acres at the top of Elk Wallow Mountain at 4,000 ft in North Carolina and can have winds up to 50mph. We are very remote and have been off the grid for 19 years. Isn;t there a smaller wind turbine available?
Equipped with an OutBack Power's Radian inverter, this hybrid wind and sun grid-tie systems will power 120-volt and 240-volt circuits. Designed with true off-grid capability, you can charge your battery bank with solar panels and a wind generator. More versatile than the systems above, these systems also have a "grid-assist mode" for folks mainly interested in being off the grid, but would like to have access to grid power.

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.
The big advantage of installing DIY solar panels is cost saving. Usually it is possible to purchase solar panel kits, using reasonable quality equipment for around $2.00 per watt. When this is compared to the average cost of solar panels installed by solar companies of around $4.00 per watt this can be a saving of $10,000 on an average 5 kW residential solar power system.
You will need some basic tools to build your diy solar panel.  First, you will need basic woodworking tools like saw, drill and screwdriver.  You will also need silicone caulk and wood glue.  For the wiring, you will need wire cutters, wire strippers, a soldering iron and solder.  You can pick up most of the tools at your local hardware store.  Radio shack sells soldering irons and solder.

Capture, store and deliver the power you need for a variety of applications, including your home or cabin. Depending on your level of expertise, professional installation may be required for this item.

An off-grid inverter must supply enough power to meet the needs of all the appliances running simultaneously. Before selecting an inverter, you must know the watts your appliances will require and their amp and surge needs. Sizing an inverter for an off-grid system, which is based on instantaneous load, is very different from sizing a grid tied inverter, which is determined by the solar panel array size. In the case of an off-grid inverter, the inverter has to provide enough energy to all the AC loads, sometimes at the same time. Say you need to simultaneously power 3,000 Watts from various appliances. For an off-grid system, you’d need an inverter that could supply at least that amount. Note that the solar array size does not enter into this inverter sizing since the inverter pulls its power from the battery bank.

The most irritating situation many consumers face after purchasing a costly wind turbine is the need of air-flow. They end up feeling that why they haven’t bought a can of wind with the turbine to see it working. To eliminate such frustrating situation, Missouri Wind and Solar has kept this kit’s cut-in speed in 6 MPH. Carries a 3 YEAR limited warranty.
Harnessing the power of the sun is a wonderful option to help combat pollution and lower your energy costs. When considering a do-it-yourself solution, the options can be limited - and quite complicated. A short list of the pros and cons of DIY solar can be found here, but this article will explore some of the lesser-known pros and cons of a DIY solar project in 2018.
Most installers overrate the available wind resource. The majority of small wind turbine installations underperforms their predictions, often by a wide margin. Since wind speed is the most important parameter for turbine energy production, getting that wrong has large consequences (the power in the wind goes with the cube of the wind speed, so double the wind speed and the power in it is 2 * 2 * 2 = 8x as much). You have to be realistic about your annual average wind speed.
DIY solar is for someone capable of reading with understanding. For any DIY that does not want to take the time to study about what he is planning to do, then DIY solar is a big fire risk for the homeowner DIY. Solar is not too difficult, but it is not easy as pie either. Wire sizes, connections, and fusing have to be undersood, and contrary to most DIY experiences with electricity, DC is a very unforgiving beast; way different from AC.
There are a lot of solar cell types that you can choose from. There are the Chinese ones, with good results, the best price, but not guaranteeing much, there are the Japanese ones with good performance, good price and the guarantee of Japanese work, and there are the American ones, with the best performance, the highest price and again, guarantees over guarantees. Choose wisely with regard to your budget. For example, a rule of thumb in 2012 would be that the cells shouldn’t sell for more than $1.3 per watt. Buy a couple of cells you think would fit your solar panel system’s budget and preferences, and move on to step #2.

Most locations getting a permit is a relatively easy task – it doesn’t require being a master electrician. In the vast majority of places you don’t need to be a licensed electrician in order to do electrical work on your own home. Anyone who’s done electrical work on their house (like adding an outlet, or rewiring a bathroom) will likely have gotten a permit for it (or should have.) So should be familiar with most of the permitting process. If they haven’t done any electrical work like that previously, then probably installing solar isn’t a good time for them to learn electrical skills.
Going forward, there is hope for the small wind future! Certification programs are under way in various places to provide real turbine performance data. In North America this is being spearheaded by the Small Wind Certification Council, which requires third-party certification of turbine performance in a standardized fashion. Manufacturers will no longer be able to fudge power curves, or specify ‘rated power’ at hurricane-force wind speeds. This will allow you, the consumer, to compare turbines on a much more even footing.
