Throw punches at the bag but donât throw yourself at the bag. Stand on your own two feet and donât fall into the bag. Keeping your balance makes for better punching power and better footwork around the heavybag. Donât use the bag to hold you up.
At the time of this writing, the installed cost of solar panels was between $7-$9 per watt: A 5 kW system would cost around $25,000-$35,000. Many utility companies offer incentives, and some subsidize as much as 50% of system costs.
A bright idea gets cheaper. Since 2007, the cost to buy a solar power system has fallen by about 50%, to an average upfront cost of $4,590 per kilowatt, says the Solar Energy Industries Association (a typical home system ranges from 3 kW to 7 kW). You would recoup your upfront cost in an average of seven to 15 years, the Solar Foundation reports.
