Solar panel power inverter is the future of energy


Within a decade, more than 35 million buildings may be generating their own solar panel  electricity (without subsidies) at prices lower than their utility offers, sufficient to power inverter  almost 10% of the country.

That’s the power inverter ful headline from the Institute for Local Self-Reliance’s latest report, Commercial Rooftop Revolution. Despite the opportunity, utilities, regulators, and policy markers are largely unprepared for the surge of local solar panel  power inverter .

In Minnesota, for example, the state’s largest utility expects just 20 megawatts of new solar panel  power inverter  in the next 13 years, according to its draft filing with the Public Utility Commission. But within 10 years, says report author John Farrell, director of ILSR’s Democratic Energy program, “unsubsidized solar panel  electricity will be so inexpensive that 200 times more solar panel  (over 4,000 megawatts) could be installed on the rooftops of Minnesota homes and businesses, providing lower cost electricity than from the utility.”

That’s just one wake up call, among many, in Commercial Rooftop Revolution. A solar panel  revolution that has been largely confined to states with generous sunshine (California) or high electricity prices (New Jersey) or both (Hawaii) will spread rapidly in the coming years. Utilities in unexpected states like Tennessee, Wisconsin, and Nebraska will face enormous competition from inexpensive rooftop solar panel  power inverter  by 2022.

Many utilities and state regulatory commissions are finding the value in solar panel  and realizing that perceived barriers aren’t as large as they had feared. Austin Energy, a Texas municipal utility, now pays a non-subsidy premium for solar panel  because it helps them offset expensive peak power inverter  purchases. In Hawaii, regulators have amended archaic limits to match renewable technology. California grid tie inverter legislators increased the amount of solar panel  allowed to use net metering to offset on-site electricity use. And Colorado and Vermont have capped costs and streamlined  solar panel  permitting.

With a solar panel  market driven by cheaper-than-electricity prices, Hawaii’s electricity system may hint at the forthcoming paradigm change. One of the state’s public utility commissioners notes that utilities need to transition from being grid tie inverter dominators to facilitators, from being inflexible to being flexible. They will need to switch from a reliance on utility-controlled, large, centralized coal and nuclear power inverter  plants to a nimble mix of flexible energy sources like energy storage, demand response, or natural gas. Already,grid tie inverter the state is one of 14 states with local or state-based CLEAN Contract (a.k.a. feed-in tariff) policies that dramatically simplify the process of going solar panel  for residential and other electric customers.

With the cost of solar panel  falling rapidly and local solar panel  challenging utility prices nationwide, ILSR’s report suggests that utilities will need to accommodate a grassroots movement toward local, affordable energy generation.

There will be more change in the next 10 years than utilities have faced in the last 100,” remarked Farrell. “And they had best get ready.”
