What troubles can arise from a lack of grid power?

I am currently at the client's office, and we are facing a power outage. To cope with this situation, we have started a diesel generator, but it can only power basic loads such as lights, computers, and other essential equipment. Unfortunately, it cannot support the use of air conditioning.
However, using a diesel generator brings several nuisances. Firstly, it generates loud noise, which hampers the productivity of the employees and disrupts smooth conduct of meetings. Additionally, the diesel generator emits a pungent odor that is unpleasant and harmful to human health. This odor contains toxic gases that are detrimental to the body.
Therefore, purchasing a solar energy system not only helps save costs but also enhances the quality of life for people. Solar energy systems provide reliable power without noise pollution or the release of harmful gases, creating a more comfortable and healthy work environment.
