How to Maximize Your Savings under NEM 3
Вставка
- Опубліковано 28 сер 2024
- California’s new Net Billing Tariff (NBT), or NEM 3.0, is the successor tariff to NEM 2.0. NEM3.0 incentivizes customers to move from the installation of solar-only systems to solar + battery systems. This evolution of residential solar systems from NEM 2.0 to NEM 3.0 was motivated by the need to match energy supply and demand in the grid through the creation of a market-driven tariff structure.
Enphase has developed a comprehensive solution that can improve homeowner ROI under the NEM 3.0 tariff mechanism. In Section 3, we will show that adding a small grid-tied battery to a solar system can significantly improve the homeowner’s electric bill offset from 55% for solar only systems to 70%-90%, while delivering a payback period of about 5 to 7 years. We will also show that this solution is very easy to design, install and commission.
Homeowners will still have a choice to opt for a larger solar and battery system that improves payback under NEM 3.0 as well as provide backup power when the grid fails.

What is the recommended ratio of solar panels kW size : battery kW storage
@@spgiants82 When designing a solar system, it’s crucial to ensure that the solar panels can consistently recharge the batteries, regardless of the time of year. For example, if you have a 5kW solar system paired with 40kWh of battery storage, the system might struggle to recharge the batteries fully if they are depleted by more than 70%. A quick way to estimate the appropriate battery size is to take your annual energy production in kilowatt-hours (kWh) and divide it by 365 days to find your daily average. Ideally, your battery capacity should be within 20-30% more or less than this daily average to maintain efficiency and reliability.
Avoided cost would be the power company not running their natural gas turbines for topping off the demand load or alternately buying wholesale power in California''s wholesale free market if that still exists after the Enron swindle.
So the IQ8 Sunlight backup is a gimmick? When the grid goes down the IQ8 does not form a microgrid and island the home from the grid and keep the lights on? Are you saying you need a full backup to do this? I am confused. Enphase marketing implies their technology islands and forms a microgrid during sunlight hours when the grid is down. You do not need a battery. If the grid is down and the sun is down a grid tied battery with IQ8 should island too. Please clearify. I thought this is what seperates ENPHASE from all the other solution options!
You still need the automatic transfer switch (IQ System Controller) to form the micro grid. Additionally, if you do sunlight backup Enphase requires the IQ Load Controller which really only allows two circuits per load controller. There are other backend software restrictions Enphase imposes too that ultimately lead us to not offer the sunlight backup to our customers as it’s more of a marketing gimmick.
Really like your videos, thank you!
Between Franklin and Enphase 5p, which do you recommend for my situation? Already have IQ8+ micros paired with 400W REC panels and looking to add battery storage. 4x 5P or 2 Franklins. Cost-wise, they're about the same. I'm leaning towards Enphase just so I can be all within their ecosystem. Franklin seems new so not sure how things might go for them.
@@shreyasdube they’re both great options, if space is a factor then Franklin is probably the better choice. Otherwise, Enphase has a great solution
@@dalerolphThanks! I ended up with 4 Enphase 5Ps. They were commissioned a couple of weeks ago and it's been great! I'm on time of use rates and making about $7/day when it's sunny.
Dale Have you heard if Solaredge is developing a metered collar device?
Could you let us know which brands are going metered collar direction?
We have confirmation from Tesla and Enphase. We have been told SolarEdge is looking into it as well as Schneider Electric. We hope someone will come to market with a universal collar for any battery backup manufacture to use and integrate with.
So how exactly can you sell your stored energy from the battery to the grid? Does enphase app automatically discharge?
Yes, there are new mode called savings mode that is linked to the utility companies export and import rates.
@@dalerolphthat’s really cool
What software do you use
We use OpenSolar, you should check them out

Riverside California and the last 4 years I've had at least an outage a year. Much less stable than what I was used to in the Midwest in tornado Alley.
Then you would want to go with the battery backup
this guy get 10K pure profit for every solar system he install..... that is the bussiness. lol
Maybe so, and his customers save money for the next 20 years. Win, win!
As he should. Thanks for the channel.
