Should I ask for a larger inverter? : r/solar

In NREL PVWatts (see sidebare), in the Advanced settings you can enter the DC to AC ratio (in your case, 8 / 6 = 1.33, pretty normal). For NYC, it estimates 10.375 MWh/year with a 6kW inverter, and 10.364 MWh/year with a 7.6kW inverter--the bigger inverter is worse! I''ve seen this type of result before when messing with DC-to-AC ratio.

Solar inverters have one core function: convert the direct current (DC) solar panels generate into an alternating current (AC) used in your home. There are two main types of home solar inverters: Microinverters attach to the back of each panel and are best for complex solar installations.. String inverters connect strings of panels in one central location and are best for simple installations.

Oversizing a PV system for more solar energy | SolarEdge

Solar panels are tested when manufactured for their performance at 25°C; when heated by a very hot summer sun, their efficiency is reduced. The increase in temperature above 25°C reduces the performance of the solar panel by the value of the temperature coefficient (a different figure in each solar cell).

The expert guide to solar panel inverters & costs [UK, 2024]

Microinverters are significantly more expensive than string inverters when you start thinking about them on a whole-system basis. If a solar panel system comprising 12 panels had a string inverter, it would cost around £1,400, whereas if it had a microinverter on each individual panel this would cost closer to £2,100.

Shade And Solar Panels: What You Need to Know

Additionally, since the cells are cut in half, the panel is less efficient at converting light into electricity and therefore produces less power than a standard solar panel of the same size. That said, for homes with significant shading issues, or those located in areas with lower levels of sunlight, half-cut solar panels may be a better option than traditional panels.

The consequences of photovoltaic panels being larger than the inverter [PDF]

6 FAQs about [The consequences of photovoltaic panels being larger than the inverter]

What happens if you oversize a PV inverter?

And when oversizing a PV array an inverter will be more often operate at or close to its rated AC output power, heat generation from the inverter may create an issue for the installation location especially if inverters are installed in a plant room or similar where air flow and heat dissipation might be limited.

Are solar panels more energy efficient than inverters?

It is very common in Australia for the total capacity of solar panels in an array to be the same as the capacity of the inverter. This has the advantage that energy will never, or almost never, be lost because of the panels producing more power than the inverter can use. But this is not much of an advantage.

Should a solar inverter be oversized?

Oversizing can make better use of the inverter’s capacity, produce more power overall, and avoid complex installs. Micro-inverters can be paired with 320W-350W solar panels, while string inverters can be paired with 8360W-9120W solar arrays, and oversizing guidelines depend on climate and other factors.

Can a solar array put out more power than an inverter?

According to the Clean Energy Council, you can have a solar array that can put out up to 30% more power than the inverter is rated for and remain within safe guidelines.

Can a PV array be oversized?

By oversizing a PV array, the DC energy output of that array can better match the rated AC power of an inverter. This means that an inverter with a lower AC rating (and thus lower cost) can be used. Consequently, this can decrease the relative cost of inverters compared to the total system cost. 4.

What does oversizing a solar panel mean?

Oversizing means that we have the capacity to produce more DC power in a system than the inverter can effectively turn into AC energy. On the surface, that would seem counterintuitive. Shouldn’t we aspire to an equal amount of DC power coming as AC power going out? This would be true if panels always produced at their maximum stated output levels.
