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.
1 Overall (Average) Solar panels cost (from recently updated figures in 2013) ranges between $1750 â $2500 per Kw of installed capacity (average Solar panel cost per kw). 2  This figure includes purchasing the equipment and cost for solar panel installation.ne need to consider that as solar panels costs diminish so is the required scale of financial incentives (e.g. FITS â Feed-In-Tariffs) that aim to make solar energy installations more affordable or financially viable and profitable.
