Solar vacuum tubes have always been more efficient than solar panels, but they were also more expensive. But solar manufacturing costs and new manufacturing innovations have brought the cost of solar vacuum tubes down. Naked Energy's spec sheets don't state the cost of these, and I suspect they're still a bit too pricey for individual households.
However, the growing demand of solar energy and modern manufacturing techniques has driven down the cost such that vacuum tube technology can provide great return on investments for applications requiring high temperatures. The principle behind solar vacuum tubes is simple. A solar vacuum tube works similar in design to a coffee thermos.
ELM Solar will distribute Naked Energy's solar products through its dealers and partners across the U.S. Tubes and pipes are most effective in heating and cooling systems. Most computers and laptops use heat pipes to cool the processor, and vacuum tubes are still used in high-end amplifiers.

Combined costs ($28,505) ÷ annual savings ($2,822) = solar payback period (10. 1 years) In this example, you'd break even in about 10. After that, you'd have roughly 15-20 more years of free electricity—adding up to significant long-term. Solar payback period is the time it takes for electricity savings, export credits, and incentives to recover the net cost of a solar PV system. High-cost electricity areas like California and the Northeast offer the fastest returns. For the average solar shopper, that translates to around $61,093 in savings over 25 years.
