Off-grid is also suitable for folks living remotely, far from power lines, since the cost of installing transmission and distribution cables is prohibitive by comparison. This off-grid system has no connection to the utility power grid. Off-grid solar systemĭIYers and people yearning for complete energy independence may choose a stand alone solar array. It will expire after that unless reauthorized by Congress.Ĭheck out DSIRE, the Database of State Incentives for Renewables & Efficiency, for all the latest information on how you can save on switching to solar energy in your state, as well as our own guide to save money on solar installation. Through the end of 2020, the federal solar tax credit is equal to 26% of the total installation cost. home in 2020, a 6kW solar installation project costs approximately $17,000 (after the federal tax credit). states vary widely in the number and extent of federal or state tax breaks, rebates, and other incentives for home solar. This prevents electricians repairing the transmission lines from getting hurt or killed by live voltage sent by your panels. Since you are connected to the grid, however, power outages also shut down your PV array. Homeowners with solar may soften the sting of higher costs during peak daytime demand because of their solar array offsetting the need for utility electricity. In some places, electric companies may charge higher rates during peak demand times. You pay a fixed monthly fee for access to the power grid – whether you actually use this service or not. However, it’s not correct to think that the utility provides you with a “free” form of solar storage through net metering. Later, homeowners “redeem” their credits when they use grid electricity because their solar array is not generating enough energy to meet demand. Whether individuals eligible for net metering receive retail or wholesale rates varies from place to place. In jurisdictions in the United States where net metering exists, homeowners receive a bill credit for the surplus. If your solar array produces an excess of electricity that you don’t consume, it’s sent to the power grid as AC to supply other homes or businesses. There are several types of solar inverters on the market, but they all do the same thing: convert the direct current (DC) electricity from the sun into the alternating current (AC) that you need to run most household appliances.Īt times when your energy demands are higher than what your panels supply, like at night or on cloudy days, the utility grid delivers electricity into your home. Online tools, like the PVWatts Calculator from the National Renewable Energy Laboratory (NREL), make the math easy for you.ĭuring the solar panel installation, the PV modules are connected to an inverter. Please visit their site for more info and Amazon to order one.Before purchasing an on-grid solar system, it’s important to determine how large of an array you need to meet all of your home energy needs. Source: The sample for this review was provided by Off Grid Tools. The Survival Axe Elite is available on the Off Grid Tools website for $89.99. Even with the minor issues I have had with this tool, I would still recommend it to someone that was looking for a tool of this type. The oxide coating has held up so far and will help protect the Survival Axe Elite while it waits to be used. The build is solid and the materials seem to be first rate. The features have been well thought out but, I would honestly only use some of the features in an emergency (mainly the hex sockets). So, what’s my bottom line here? The Off Grid Tools Survival Axe Elite is good. The blade did cut well and the way the system is designed makes it a little more ergonomic when cutting. I am just scared that I will hit the back of the blade making it close on my fingers. First, let me say I love the fact that the saw feature is included on this tool, that being said I think the tool would benefit from a redesign of the locking mechanism. I did try out the nail puller and it also performed well. The grip was comfortable for both chopping and hammering. The hammer was also good at what it does, hammer. The hatchet blade is good for chopping, I wish that the blade was sharpened a little better, I believe this would make chopping wood easier. I mainly tested the Survival Axe Elite by using the hatchet, hammer and saw blade. As with the blade lock both of these items are low enough on the handle so they should not interfere with normal use. Both would seem to function well, but I must admit I did not try out the glass breaker. I mentioned the glass breaker before, but the handle also has a seatbelt cutter built into it.
