I did not understand how to couple both solar and gasifer to each other help me.
The below mentioned review discusses solar pyrolysis of biomass. Best wishes.

How to integrate the biomass gasifier and solar collector to produce electricity?
Solar collectors produce thermal energy which can be directed to the biomass gasifier to provide the required thermal energy to produces syngas (CO and H2). You can add a gas separator downstream the gasifier to separate H2 gas from CO gas. The produced H2 gas can then be used as a feedstock to proton exchange membrane (PEM) fuel cells to produce electricity.
Hope this helps answer your question and good luck.
You can produce steam through solar collector which can be use in gasification to increase hydrogen fraction in syngas. These syngas use in IC engine to produce electricity or separate hydrogen from syngas and utilize in fuel cell technology.
Thanks Yehia F. Khalil sir and Anil Kumar Sakhiya and please provide some papers for me related to this.
Yehia F. Khalil Mohd Parvez Good morning this is not my area of expertise but I would like to help. I have been advised that during syngas production from biomass gasification, special care should be taken to avoid that residual CO gas can be carried by the syngas since CO is harmful to fuel cells, thus a stringent filter stage applies.
You would also need to remove the tar content in the CO stream prior to produce syn gas.
And I would like to mention a more conventional alternative. You may use a lean-burn engine to use CO gas from biomass gasifier. These motors are though enough to not being affected by the tar in the gas stream. Their role in the microgrid would be similar to that played by a diesel generator still relying on renews. - Hope this can be of any help, BR!
Since gasification is carried out at fairly high temperature, all the energy requirement may not feasible to get from solar. A few possible alternatives;
1. Produce steam by using solar energy and do steam gasification
2. Do biomass pretreatment (drying/torrefaction/mild pyrolysis) by using solar energy and use pretreated biomass in the gasifier
3. Energy requirement of gasification is partially supplied by concentrated solar energy and partially by air gasification (in this case equivalence ratio can be lower than typical values)
The choice depends on the solar intensity of the location as well as the capital investment.
