Solar Photovoltaic FAQ
- What's the first step if I
want solar photovoltaic power to pay for my electric needs?
Contact us, of course! We can use computer based satellite imagery to view your proposed site and learn the basics of your project. We'll discuss your goals and expectations, and, well, get to know each other a bit!
- What does NJSC do to determine if my site receives
sufficient sunlight?
We measure the available sunlight (insolation) at your proposed site using state-of-the-art tools and software from which we can determine if your site probably capable of meeting the 80% efficiency requirement. Then, depending on other factors such as panel and inverter efficiencies, we can determine generation levels.
- Will my photovoltaic system pay for itself? If so, when and how?
Assuming your site will qualify for available state and federal incentives, it surely will pay for itself. When, however, is a question that's frequently over simplified. We developed our own software which allows us to model return on investment based on factors including the rising cost of electricity, solar certificate (SREC) values, loan costs if applicable, and more. We'll go over these assumptions with you, entering realistic numbers. Your projected return on investment analysis will then be personalized and you'll have a good feel for how it was calculated.
- What solar rebates and incentives are available in New
Jersey and how is that likely to change?
New Jersey offers a rebate for solar installations (up to a certain size) but rebate values are in flux. SRECs (solar renewable energy certificates) provide the largest percentage of state incentives. Let us explain the state's SREC program to you and how we can facilitate obtaining maximum value for your SRECs.
- What will a system cost that covers my entire electricity
usage?
Your total PV system cost depends on the parts cost, installation cost, and how productive the system is. Efficient design can substantially shorten the payback time. We perform a complete analysis as part of our solar feasibility service.
- What are the "hidden" and ongoing costs of a
photovoltaic system?
Many systems are priced without a good grounding system, which cuts costs but exposes the system to failure if struck by lightning. Other than that, photovoltaic systems contain no moving parts and are highly reliable. Our financial model allows us to make a maintenance cost assumption nonetheless, such as inverter replacement during the life of the system.
- How will I be credited for producing more power than I use?
Most systems are connected to the utility grid. If so, on a daily basis you "bank" power mid-day as your system produces more than you consume. As the sun goes down you draw power back from the grid. Ideally, by the end of the year your meter will have spun backward as much as it spun forward. If you produced more than you used your utility will buy it back from you annually, paying you their cost of production (wholesale rate). Over sizing a system is not cost effective.
- Are advancements in solar
panels or equipment going render what I install today
obsolete?
While advancements are always possible, a photovoltaic system installed today will continue saving you money regardless of any new advancement - which do seem painfully slow coming. Waiting for unforeseen technology amounts to paying the utility company for your power while hoping for sunnier days.
- How do I know a good solar installer from a not-so-good
installer?
Even installers with happy customers may have installed a photovoltaic system that's not optimal and would take longer to pay for itself than it should. We measure the site ourselves and perform "what if" scenarios to arrive at the most efficient solution.
