Pooling Resources: North Rim HOA

Commercial Case Study

North Rim HOA
Mission Valley, cA


The North Rim community leaders were looking for a way to save energy costs for their community center, which includes a large swimming pool. They were also interested in offsetting energy costs to light for the community’s tennis courts.


A 60-panel ground mount solar panel array was built on a nearby hillside. The solar system was designed and installed to deliver electricity through two separate meters. The commercial solar system turns Southern California sunshine into renewable energy that benefits all the residents of the multi-family North Rim community. The energy needs of the large pool facility now draws the bulk of its power needs directly from San Diego sunshine. The tennis courts’ energy costs are completely covered by selling energy back to the utility during the day.

Customer Benefit

The energy meter for the community pool now consumes 75% solar energy. The tennis courts take advantage of net metering to offset 100% of their energy costs to light the courts. After the success of the community-shared solar system, the community HOA leaders established HES Solar as the association’s preferred solar company. HES Solar could then offer home solar systems to each individual unit in the community. The growing solar partnership allows San Diegans to benefit directly and indirectly from the cost savings brought by solar energy production

The North Rim HOA made the decision to install a common-area solar array, yielding energy savings of approximately $12,000 to $18,000 per year. These cost savings will expand as electricity rates rise. The savings allowed the Association to offset other increasing expenses, such as water, insurance, and services. The HES Solar array provided an effective and reliable means to mitigate one of our community’s large, recurring expenses.

Net Energy Metering 3.0 (NEM 3.0) is the incoming law created by the California Public Utilities Commission (CPUC). The new tariffs and fees will impact both residential and commercial solar systems built in California. 

As this notice is posted in November of 2022, the Proposed Decision from the CPUC outlining the proposed NEM 3.0 terms is expected soon. This comes after a year’s delay. Once the new agreement is finalized and passed into law, there will exist a designation of the deadline under which new systems will continue to qualify for NEM 2.0 rates. 

The new NEM 3.0 rates will be designed to lower the value of electricity during the daytime hours, when solar is producing, and increase the value of electricity during the evening hours, when solar homes and businesses purchase electricity. In short, NEM 3.0 will create a “sell low, buy high” proposition to new solar system owners. 

To Californians looking to install a solar system on their home or commercial building, the NEM 2.0 rates will be preferred. As of this post, the solar industry does not know the details of how different the NEM 3.0 rates will be from the NEM 2.0 rates.
