This article will discuss the advantages of using microinverters with AC coupling for residential, single-phase applications. The two leading microinverter manufacturers in the U.S. market include...
Last Tuesday, leaders of the Baker Administration’s Department of Energy Resources (DOER) released their final plan for the state’s new solar incentive, the Solar Massachusetts Renewable Energy...
How do you value solar energy production? That is a question several prominent utilities and Public Utility Commissions (PUCs) are debating across the country as initial Net Energy Metering (NEM)...
As a state without a solar carve-out (no SREC market), and no net metering, Tennessee is expected to install 476 MW of solar electricity over the next five years, more than five times the solar...
Under the proposed incentive, eight blocks of 200 MW each would be opened up to encourage 1600 MW of additional solar capacity in the state over the next several years. Within each block, solar...
What do you do when your array is producing more energy than you consume? Or when you want to go solar but your available property has a suboptimal solar resource? In the absence of a battery backup...
This evolving picture routinely delivers a combination of encouraging and sometimes disheartening developments. While the industry rejoiced with the extension of the federal Investment Tax Credit...
Measuring AC energy delivered by a residential PV system can be broken into two main categories, revenue-grade and non-revenue grade. You might ask then, “Why would I need revenue grade data?” To...
The design of PV systems can be fairly simple as well as extremely complex. No matter how difficult or easy, it is important to document the design process. Doing so will help flush out issues...
One of the main considerations to AC-coupling design is the ratio between the Grid-Tie inverter (GTI) and the Battery-Based inverter (BBI). Why? There are conditions that might occur when the site...
