1, imbalance of resource distribution and configuration. Household photovoltaic system need space to carrying system equipment, single-family villas 【 Single-family villas which single-family house, have an independent space, on the private garden of territory, under the basement, is a detached house of illicit close sex is very strong, before and after the performance for the up and down or so belong to independent space, generally have around the area of the building of green space, yard, basketball court, swimming pool, pavilion, etc. 】 And cement plate is suitable for construction.
but, cement plate room in the majority with underdeveloped rural areas, the, general corporate investors, as well as individual citizens are not considered, because of the huge difference between costs and benefits ( Hooked up to the poor poor, less electricity, electricity prices lead to low income) 。 Single-family villas is concentrated in developed areas and the economic condition is good, but the minority after all, it is difficult to scale.
best of all, the developed areas of rural area, the center of the city surrounding villages, cement room, and concentrated, is advantageous for the development and utilization.
the following to the second reason & ndash; —
2, upfront costs too much, payback period of investment' The payback period of investment is also referred to as 'investment recovery period'. 】 Is longer than the other.
just 8 - current household photovoltaic system The investment cost of 10 yuan/W, 10 kw system is about 100000 yuan, annual power generation 10000 degrees, total revenue including save charge income, income of subsidies, and the Internet charge income of three parts, 1 year is about 10000 multivariate, need eight Nine years. In 20 years, net income of about 100000 yuan, the yield about 10%.
so, are you willing to upfront investment of 100000 yuan, at the same time to undertake plant risk of loss, damage, unable to get subsidy, etc. 10 years later, obtain 200000 yuan of the total income?
the earnings or actually make money more than bank deposits, in the case of all kinds of system security, it is worth of ordinary people to invest in ~ ~ ~
this is the third reason & ndash; —
3, single development mode, there are risks. On the one hand, do the best solarcity, can provide loans for the owners, and a variety of loan options, and perfect after-sales service and guarantee, maximum reduce the risk of the owner, to provide security guarantees.
at present has not yet been able to provide such perfect supporting services, inc. ( My company is exploring and actively carry out such projects, in order to let household photovoltaic system into) 。
4, environmental protection consciousness. This would not be here ~
to summarize, I think, household photovoltaic power generation systems market is very broad, but restricted by the policy supporting is not complete, weak market environment, the high cost, domestic has not been large-scale development ( But have been successful cases abroad, the United States, Germany is model) 。 But maybe one day, just like, like taobao electricity in spring?
