• I want to go solar, but shouldn’t I wait for the technology to develop further?

    Solar technology has advanced steadily over the last several decades to the point where it is reliable, efficient, and cost effective. Additionally, current rebates and incentives (which offset a large portion of the cost) are being phased out and will not be available in coming years.

  • Why do you need a site visit – can I get an estimate over the phone or online?

    While we can give you a ballpark estimate, Luminalt will need to visit your site before offering a firm quote. This is to identify all costs upfront and give you a comprehensive price. Before signing an agreement, be sure the solar company has visited your site to verify your quote.

  • My property is in a foggy area – what are my solar options?

    The same as everywhere else! While fog can slightly impact system performance, many business owners in the foggiest parts of the Bay Area are zeroing out their electric bills each year with solar. 

  • How do I know which is right for me – solar hot water or solar electric?

    The answer can depend on a number of factors including how much electricity and hot water you use and when, which rate schedule you are on, and available rebates. Contact us for a free quote and bill analysis.

  • How long will the solar system last?

    All Luminalt systems come with a 25 year module production warranty and are built to last 30+ years. Because there are few moving parts, solar systems generally need very little maintenance and last well beyond their warranted lifetime. Additionally, Luminalt is all too familiar with the local maritime climate and only uses aluminum and stainless steel parts to protect your system from the elements.

  • What maintenance does a solar system require?

    Because solar systems have very few moving parts, maintenance is extremely minimal. Additionally, any costs that are anticipated (e.g. inverter replacement) are included in the financial analysis of every quote we offer – so there are no hidden future costs.

  • Is a solar system heavy – will I need to reinforce my roof?

    No. Solar systems have an average load of 3-4 lbs. per square foot. This is less than a layer of composite roof shingles.

  • What happens to the excess power generated by my system? Can I sell it back to PG&E?

    Beginning in 2011, PG&E customers will have the option of receiving payment for any excess generation sent back to the grid at the end of their True-Up year. See PG&E for details, or contact us.

  • What does an average solar system cost?

    Rebates, incentives, and financing can make going solar possible for almost every budget. If your business has tax equity and high utility bills, solar is likely a good investment. Contact us to discuss your specific situation or to receive a free custom proposal.

  • What if I don’t know my PG&E usage – can I still receive a proposal?

    Yes. The more information you provide, the more accurate your proposal analysis will be. However, if you have just moved in or don’t have access to past records, contact us and we’ll discuss ways to estimate your usage.
