p>We have seen that people <strong>dual wire a house for solar panels</strong> so there's no technical problem with it, but to know if you're allowed you'd need to check with your local building authorities to be sure it doesn't violate Building code. </p> <p>Our two cents - there is for sure losses due to the inverter, but for a load as small as lighting, it may not be worth the added effort to wire it for DC, particularly if you use <a href="/guides/1093/product-of-the-month-led-filament-bulbs/" target="_blank"><strong>LED lighting</strong></a>. Since you’re going to install an inverter anyway, it really boils down to the amount of lights you think you’ll need, what that draw is, and how much cost and effort is required to run DC as well.</p> <p>Please let us know what you finally decide, that's a great question and a great ide, thanks! </p
