Q: How much do these systems cost and how much money will I save each year? How long will it take to pay back my investment?
A: The size of the system is the largest determinant of the price, and the savings rise accordingly. In most cases, the payback period for the investment in a photovoltaic system is roughly 5 years with internal rates of return ranging from 15% to 25%, depending on the avoided cost of energy and the site-specific design and resulting costs.

Q: What subsidies are available?
A: Commercial solar buyers benefit from a 30% federal tax credit (though 2019) and accelerated federal depreciation. Combined, these tax benefits typically defray as much as 70% of the out-of-pocket cost of solar. Entero Energy will give you the most current information and include that in your proposal with detailed pro forma cash flow statements for a variety of appropriate financing mechanisms.

Q: Is financing available?
A: The best source of financing is usually the bank, finance company, or mortgage company with whom you currently work. If you like, we’re happy to make arrangements with a number of independent solar finance partners we’ve worked with on other projects.

Q: We don’t own the property on/in which we operate. Can we still go solar?
A: Yes, it’s relatively commonplace for property owners to allow their tenants to make improvements in their facilities and we have many customers who are tenants with long-term leases.

Q: Since the return on investment hinges on selling power to my utility, how can I be confident this will be accurately accounted for?
A: The power you generate is metered by your inverter and the utility meter tracks power in both directions – both power you buy and power you sell back to the utility. Plus, you can track your production and the power you export via our online monitoring software. Finally, you’ll receive a monthly statement from your utility company. All these provide ample reassurance that the accounting will be done, as it has been done for the over 100,000 interconnected photovoltaic systems all across the nation.

Q: What are the critical assumptions for modeling ROI?
A: The key drivers are avoided cost of power no longer purchased, the site-specific system design and cost, and the value of the state and federal subsidies.

Q: I hear XXXXXXX’s modules are the most efficient. Wouldn’t those be the best choice?
There are some considerable performance differences between manufacturer’s products and often there are differences within a given manufacturer’s product line. As you might expect, greater efficiency carries a higher price. In every case, Entero Energy seeks to design the most cost-effective solution, maximizing your long-term return on investment while minimizing the initial investment and therefore will provide an assessment of the relative merits of all major solar module technologies.

Q: I hear XXXXXXX’s modules are the cheapest. Wouldn’t those be the best choice?
As with most products, you get what you pay for. Given the 25-year performance warranties solar module manufacturers offer, Entero Energy screens module manufacturers not only for product quality and performance, but also for long-term financial viability, since a 25-year warranty from a company that went out of business creates a risk that can overwhelm and potential savings from using discount modules. We typically choose only diversified manufacturers who can weather the ups and downs of the business cycle to ensure long-term warranty coverage is maintained. In fact, many so-called “Tier One” manufacturers do not pass our financial health screen due to limited track record, lack of consistent profitability, or opaque financial data.

Q: I’ve never heard of the companies that make inverters (e.g., SMA, ABB, Schneider, etc.). How can I trust them?
A: Entero Energy sources inverters from only the largest, best-capitalized manufacturers for quality, longevity, and long-term financial viability.
