With climate changes and rising energy prices, many designers, builders, remodelers, and homeowners now realize that building-integrated solar can be particularly cost-effective in tandem with super-efficiency, providing measurable savings to owners.  The bottom line: Solar energy is back in a big way, but the only means of determining which measures are most cost-effective is to undertake  computer energy modeling, preferably with a flexible software tool that provides consistent, understandable results. There are several results-oriented solar-design tools that I have found to be useful in providing practical solutions to common design problems.

At PVPower, we're in the process of developing some simple, accurate and easy-to-use solar design, planning and proposal tools. The first portion the software, System Designer, is available at http://systemdesigner.pvpower.com - I'd love to hear if anyone has feedback.

System Designer takes roof size and a few other factors and builds working module and inverter combinations.

Regards,
Dan
