We are caught in the horn of a dilemma. Chinese solar panels are the lowest cost panels to generate solar power. Buying from China on one hand reduces investment costs but bolsters their solar energy business. But given the massive requirements of solar panels , the US government should support any investment in the USA to produce more solar panels. One should not await for thin films or concentrated solar (none of which have lower costs than current poly silicon solar panel ) but support a massive build up of solar power. India promises to have about 415 GW of solar installed by 2030(?) . Questionable but they are making rapid progress in attaining this goal. China is way ahead. A big problem in the US is the lack of sufficient incentives for home owners to install solar panels on roofs. I understand that some incentives are available. Utilities cannot include these costs in their rate base and moreover have to purchase surplus power from home generators at retail tariff. If utilities were allowed to finance home owners wishing to put up solar panels or set up roof top solar for retail commercial customers at no cost and allowed to include these investment costs as part of their rateable assets, they may have an incentive to promote roof top solar which has a huge potential. Instead of focusing on thin films and concentrated solar , which may be practical in tropical areas such as Morocco , where the World Bank financed a project. But I haven't seen any data on their economic efficiency. Let's get going with the technology we have . The US solar capacity addition projections as outlined in the article are pathetic. We need to adopt the Chinese industrial strategy as far as solar panels are concerned. Any innovation should be supported but let the best strategy NOT hold back what is feasible now.
