No where near 50% is lost these days in modern AC/DC or DC/AC conversion devices.
Solar panel DC/AC inverters run at 95% to 98% conversion efficiency.
Likewise modern AC/DC converters can easily achieve 90 to 95% conversion efficiency.
Unless he uses very bulky low voltage, high current cables, he could easily be losing 3-5% of transmitted DC power in those.
He would be better off keeping his residence on AC and covering his roof with as many solar panels as he can fit.
