I do not need physics to understand that people feel they are entitled to installing their own power source but they have to understand what they feel is their right is not always true. So they stopped granting new pv installations until they could upgrade the grid to handle 2 way flows. Their grid was not designed for more local generation then what could be consumed. That is the main reason Hawaii chose to limit new solar installations. ![]() So even if the loads may be local if there is more power being generated (more and more homes getting pv) then what is not used will go somewhere and that may be farther back up the grid to other loads. While it is easy to justify and believe the power is going to local loads you have to remember the electricity will go to the least resistance place instantly. I know the grid is not designed for 2 way operation based on my past history as an EE. We can either abide by them or go totally off grid and power our own needs and that won't happen soon because it is too expensive for the homeowner. A simple Google search on distributed generation would suggest there are other opinions that may not be incorrect in their thinking that distributed generation helps the grid and may be more efficient.Maybe you are correct but again the POCO's own the grid and write the rules. What specifically can get damaged from an infrastructure standpoint from power flowing in two directions? Please consider how the power flows to the closest other loads on the same transformer first then onto the distribution network where it most likely serves the loads down stream of a substation which actually reduces the load at a substation. Physics tells us that transformers are bidirectional. A simple Google search on distributed generation would suggest there are other opinions that may not be incorrect in their thinking that distributed generation helps the grid and may be more efficient. Please explain the physics of the shock to the system if I were to turn off my breaker when I was generating 6kW of back feed or running my dryer and oven when I shut off the power? Solar eclipse? Even that concern was debunked years ago. Turning off my oven or electric dryer is more of a shock to my system than my solar system will ever produce. ![]() What solar systems have you seen that "suddenly" stop sending power? My systems gradually taper off on cloudy days. A solar home is not always continuous and the sudden on / off of sending power can cause the POCO to have issues.Īll those people that really think they are helping the POCO with a solar installation are incorrect in their thinking.Physics tells us that transformers are bidirectional. the grid was designed for sending power one way not 2 ways and the infrastructure may suffer from that type of distribution. A solar home is not always continuous and the sudden on / off of sending power can cause the POCO to have issues.Īll those people that really think they are helping the POCO with a solar installation are incorrect in their thinking. Also the grid was designed for sending power one way not 2 ways and the infrastructure may suffer from that type of distribution. That may be true for as much as 40% of the day but not for 100%. So it’s explained as a solar generation problem not a draw loading problem as I understand it.Again most people are uninformed that solar will reduce the load on the grid. The are asking for information about how many ev are present on the circle as an excuse to upgrade the transformer to get around the expense. They have a problem issuing a permit for solar which takes the load off the transformer. ![]() They don’t have a problem building the house with the additional load they have a permit for that already. If that were true then they wouldn’t have a problem issuing a solar installation permit.
