What Is Bias? A bias is a tendency. Most biasesâlike the preference to eat food instead of paper clipsâare helpful. But cognitive shortcuts can cause problems when we're not aware of them and apply them inappropriately, leading to rash decisions or discriminatory practices.
The average solar energy system size in the U.S is approximately 5 kilowatts (kW). Based on the average price of $3.36/watt, a 5kW system would cost $11,760 after tax credits. Below are some average 2015 quotes for other solar energy systems by size: 6kW solar energy system cost: $15,000. 8kW solar energy system cost: $20,000.
How much do solar panels cost? The cost of a solar electricity system varies a lot based on whether tax credits or rebates are available to you. It's as cheap as free, where incentives pay for 100% of the cost of the system. On the other extreme, with no incentives and a higher-than average cost of install, a system might cost $53,000.
