10 Questions to consider before installing a photovoltaic system on your facility
- solar photovoltaic roof systemphotovoltatic roofing installationIs the roof area completely free from shade during all daylight hours all year round? If you facility has a sloped roofing system, is the south facing slope large enough for the photovoltaic system which best fits the facility’s needs?
- Is the area of the rooftop large enough to support the PV system without causing a safety hazard or preventing access to equipment?
- If using a racking system, does the racking system allow for proper access to equipment and panels for maintenance or repairs?
- Is the structural support of the building sufficient for the proposed PV system dead loads, snow loads, and wind uplift resistance?
- Will the roof system last 20-30 years to match the life of the PV system? The roof system is extremely expensive to replace during the lifetime of the PV system.
- Will the solar system affect the warranty of my roof system and are the installers certified to work on that roof system without voiding the warranty?
- Which type of solar system best fits my needs? A thin film fully adhered PV system may be more suitable than a traditional roof mounted crystalline silicone PV system. Cost of installation, structural support, system performance, roof type, and available rooftop space should all be considered.
- Are government or other rebates, incentives, or credits available?
- What is the projected payback and ROI on the PV system?
- Is financing, capital lease, rooftop rental, or a solar power purchase agreement available?
