SolarEdge Vs. Microinverters

SolarEdge Vs. Microinverters

With so many options on equipment, it is easy to get lost in the decision making process. One of the most common customer questions is the difference between microinverters and a system like SolarEdge that incorporates DC optimizers with a string inverter. First, let’s look at the ways these two systems would be the same. Both SolarEdge and microinverters will maximize the power from each individual solar module with maximum power point tracking (MPPT) technology. Having an MPPT device at each solar module helps mitigate shade and orientation issues that can occur with the standard string inverters. Another common element is that both SolarEdge and microinverter systems will provide module level monitoring so you can see how each solar module is performing individually. Both systems also meet the 2014 NEC Rapid shutdown requirements in that if the system is shutdown with the disconnects that are accessible at ground level, the conductors from the roof will not be energized. So, how are microinverters and SolarEdge different? It’s all about where the power is converted from AC to DC. The solar modules produce DC power and a microinverter converts that DC power to AC power at the solar module. In a SolarEdge system, there are DC optimizers that do the maximum power point tracking at the module but they don’t convert the power to AC. The “conditioned” DC power flows in the conductors that come down from the roof and it is converted to AC power at the central inverter which is typically installed near the main service panel of the building. Now for the fun part…. Which one is best? Everyone in the solar industry has an opinion and the bottom line is you have to decide for yourself. Let’s look at some of the factors that will help you make this decision. Cost The cost of the whole system needs to be considered in this. When buying microinverters, you will pay for the microinverters, the monitoring system and the trunk cable (which is a separate part for some brands and not others). When purchasing the SolarEdge system you will buy the DC optimizers, the string inverter and possibly a monitoring option depending on how you want the monitoring to operate. The individual microinverters will cost more than the DC optimizers (you are paying for all the DC to AC conversion electronics in every microinverter). The monitoring equipment is typically the same cost for either system. Then with SolarEdge, you have to buy the inverter. The result is the total system cost on microinverters less than SolarEdge if you are doing a small system (under 3.8kw) and microinverters cost more...

Duke Energy Attempt to Foot Home Solar With The Bill, Fails

A recent settlement brought an end to an attempt by Duke Energy Carolinas to shoulder North Carolina residents switching to solar with hefty fixed rate increases. To help fund a proposed $13 billion grid modernization program for the state, Duke Energy sought to foot North Carolinians switching to solar with the bill by increasing their utility costs up to 50% according to Vote Solar’s Regulatory Director Caroline Golin. Opponents against Duke’s fixed utility rate increases argued the charges would undermine customer’s ability to utilize net metering payments, where people make money for selling the excess power their home generates back to the grid. Duke’s $13 billion Power/Forward Carolinas grid proposal, which was introduced last February, set out to modernize the state’s power grid and “support renewable energy initiatives.” Upon closer inspection of the bill, however, solar supporters in North Carolina discovered it did the very opposite by targeting people who used net-metering with higher out of pocket costs to pay for the utility company’s upgrades. “…Duke’s plan puts solar out of reach for customers, makes it much harder for clean energy companies to survive, and makes it more expensive to do business in North Carolina,” Golin writes in her blog. The recent settlement with Duke has lowered the time period of the modernization initiative from 10 to four ears, and cuts spending down to $2.5 billion, reducing the potential rate increases that will be seen by customers. The decision comes as an added win for the state’s clean energy advocates as the energy company recently rolled out a $62 million solar rebate program in January, paying residents back up to $0.60 per installed watt.

Only 600 spots left for North Carolina’s huge home solar rebate

Only 600 spots left for North Carolina’s huge home solar rebate

As summer ramps up on the east coast, people in North Carolina are lining up to get a chunk of the state’s $62 million solar rebate. Last month the North Carolina Utilities Commision approved Duke Energy’s rebate program, which is aimed at reducing the upfront costs of installing solar panels, shaving 40-50% off the cost of home solar installation when combined with the federal tax credit. The North Carolina Solar Rebate Program is capped at 5,000 kW for home solar, or roughly the equivalent of 600 homes. Under the program, residential customers will be able to earn back $0.60 per watt, and nonresidential customers $0.50 per watt. The typical North Carolina home is expected to make between $3,000 to $5,000, with the maximum rebate amount capped at $6,000. The North Carolina Utilities Commission decision to pass the rebate stems from House Bill 589, which passed last year in an effort to encourage more solar ownership. Upon success of the Duke Energy rebate last month, the company has filed two more renewable energy programs to expand renewable options for the 3.2 million customers it serves in the state. “Our customers want more renewable energy options and both these programs will provide alternatives to on-site solar power,” said David Fountain, Duke Energy’s North Carolina president. “We look forward to working with our large customers as well as environmental organizations, municipalities and solar developers to bring these offerings to areas where they are most desired.” North Carolina is second in the nation for solar capacity. Sign ups for the rebate program begin at the start of summer, Monday, July 9 2018. To learn more how to qualify for a chunk of the change Duke Energy is offering solar homeowners in North Carolina before the program fills up, contact GoGreenSolar.com or call (888) 338-0183....

California Now Requires Solar Panels For New Homes

California Now Requires Solar Panels For New Homes

The California Energy Commission got one step closer to upholding the state’s pledge to receive all its power from renewables by 2045, ratifying a mandate this week that requires solar installations on all new homes built after 2020. The vote has historical precedence, making California one of the first governments in the world to take such sweeping measures to encourage the use of renewable energy. The monumental decision which the commission passed 5 to 0, Wednesday, May 9, applies to homes, condos, and apartments, only making exceptions for buildings constructed in the shade. “Adoption of these standards represents a quantum leap in the statewide building standards,” the Wall Street Journal quoted senior engineer with the California Building Industry Association Bob Raymer. “You can bet every one of the other 49 states will be watching to see what happens.” Currently 15 to 20% of new single-family homes in California take advantage of solar. The legislation is expected to increase the cost of building a new home to code by $9,500. However research shows the extra costs will be recouped over the life of the home due to decreased energy bills, saving owners $50,000 to $60,000 in operating expenses over a 25 year period. New structures that are built with the mandated solar installations after 2020 would still be able to apply for the California Solar Initiative rebates. It is still unclear how hard this will impact the program’s funds that reimburses consumers based on system performance. It is likely, however, the forecasted increase in solar installments due to the legislation will exhaust the state’s incentivized rebate budget sooner than anticipated. While such an increase in solar installations will be good news for the environment and the homeowners that profit from the rewards, it will also increase pressure on those waiting for an economically opportune time to switch to solar....
